How to configure Hue for your Hadoop cluster

How to configure Hue for your Hadoop cluster

Hue is a lightweight Web server that lets you use Hadoop directly from your browser. Hue is just a ‘view on top of any Hadoop distribution’ and can be installed on any machine.

There are multiples ways (cf. ‘Download’ section of to install Hue. The next step is then to configure Hue to point to your Hadoop cluster. By default Hue assumes a local cluster (i.e. there is only one machine) is present. In order to interact with a real cluster, Hue needs to know on which hosts are distributed the Hadoop services.



Where is my hue.ini?

Hue main configuration happens in a hue.ini file. It lists a lot of options but essentially what are the addresses and ports of HDFS, YARN, Oozie, Hive… Depending on the distribution you installed the ini file is located:

  • CDH package: /etc/hue/conf/hue.ini
  • A tarball release: /usr/share/desktop/conf/hue.ini
  • Development version: desktop/conf/pseudo-distributed.ini
  • Cloudera Manager: CM generates all the hue.ini for you, so no hassle 😉 /var/run/cloudera-scm-agent/process/`ls -alrt /var/run/cloudera-scm-agent/process | grep HUE | tail -1 | awk ‘{print $9}’`/hue.ini

To override a value in Cloudera Manager, you need to enter verbatim each mini section from below into the Hue Safety Valve: Hue Service → Configuration → Service-Wide → Advanced → Hue Service Advanced Configuration Snippet (Safety Valve) for hue_safety_valve.ini


At any time, you can see the path to the hue.ini and what are its values on the /desktop/dump_config page. Then, for each Hadoop Service, Hue contains a section that needs to be updated with the correct hostnames and ports. Here is an example of the Hive section in the ini file:


  # Host where HiveServer2 is running.


To point to another server, just replaced the host value by ‘’:


  # Host where HiveServer2 is running.

Note: Any line starting with a # is considered as a comment so is not used.

Note: The list of mis-configured services are listed on the /about/admin_wizard page.

Note: After each change in the ini file, Hue should be restarted to pick it up.

Note: In some cases, as explained in how to configure Hadoop for Hue documentation, the API of these services needs to be turned on and Hue set as proxy user.


Here are the main sections that you will need to update in order to have each service accessible in Hue:


This is required for listing or creating files. Replace localhost by the real address of the NameNode (usually http://localhost:50070).

Enter this in hdfs-site.xml to enable WebHDFS in the NameNode and DataNodes:


Configure Hue as a proxy user for all other users and groups, meaning it may submit a request on behalf of any other user. Add to core-site.xml:


Then, if the Namenode is on another host than Hue, don’t forget to update in the hue.ini:




      # Enter the filesystem uri

      # Use WebHdfs/HttpFs as the communication mechanism.
      # Domain should be the NameNode or HttpFs host.


The Resource Manager is often on http://localhost:8088 by default. The ProxyServer and Job History servers also needs to be specified. Then Job Browser will let you list and kill running applications and get their logs.




      # Enter the host on which you are running the ResourceManager

      # Whether to submit jobs to this cluster

      # URL of the ResourceManager API

      # URL of the ProxyServer API

      # URL of the HistoryServer API


Here we need a running HiveServer2 in order to send SQL queries.


  # Host where HiveServer2 is running.

If HiveServer2 is on another machine and you are using security or customized HiveServer2 configuration, you will need to copy the hive-site.xml on the Hue machine too:


  # Host where HiveServer2 is running.

  # Hive configuration directory, where hive-site.xml is located</span>


We need to specify one of the Impalad address for interactive SQL in the Impala app.


  # Host of the Impala Server (one of the Impalad)

Solr Search

We just need to specify the address of a Solr Cloud (or non Cloud Solr), then interactive dashboards capabilities are unleashed!


  # URL of the Solr Server


An Oozie server should be up and running before submitting or monitoring workflows.


  # The URL where the Oozie service runs on.


The Pig Editor requires Oozie to be setup with its sharelib.


The HBase app works with a HBase Thrift Server version 1. It lets you browse, query and edit HBase tables.


  # Comma-separated list of HBase Thrift server 1 for clusters in the format of '(name|host:port)'.


Hue just needs to point to the machine with the Sentry server running.


  # Hostname or IP of server.



And that’s it! Now Hue will let you do Big Data directly from your browser without touching the command line! You can then follow-up with some tutorials.

As usual feel free to comment and send feedback on the hue-user list or @gethue!

    hi, i have a question about how to configuration hue with federation namenode? Is Hue have a feature to contact a multiple namenode (federation) with one server hue, or do I have to create multiple hue on multiple namenode? Thank’s before

  2. what do you mean everything should be transparent? or do you mean that hue could read every namespace on every namenode (so it’s like a namespcae combination from multiple namenode) on single hue?

  3. Sorry but i’m still confuse with your explanation, this is the scenario:
    I have a double namenode(namenode 1 and namenode 2) and 5 datanode, i have install hue1 one namenode1 and hue2 on namenode2
    I configure all namenodes on federation mode with the same datanode.
    If i upload some data(data1) from namenode1 trough hue1, I can’t read the data1 through hue2, but if I configured hue2 to pointing on namenode1, sure it can read the data1 but i can’t upload any other data trough namenode2 or even read the data on namenode2.
    if I pointing two webhdfs via pseudo-distributed.ini on two namenode on the single hue like this:
    the service won’t up and give me an error message
    So, what should I configure to make a single hue can read and upload the data from both namenode? Thank’s before

  4. I have success configured 2 namenode with viewfs and I can access those 2 namenode on one client just with “hdfs dfs -ls /” command, how can i configure hue to do that thing?

  22. Manasa 1 year ago

    Hi Team,
    Firstly I would thank you for providing a wonderful UI for hadoop. Please consider the below scenario:
    1.I am connecting from my local system to Hue which is on a remote system.
    2.Hue connects to cluster which is configured remotely(Hue and cluster are in different locations)

    In this case can hue connect to cluster remotely ?If yes ,then will the data processing performance of this case be the same as hue present within in the cluster?

    • Hue Team 1 year ago

      Thanks Manasa! Hue can connect to any cluster but of course the network needs to allow that (ie. firewall configurations). The data processing is done by the Hadoop cluster(s) and not Hue itself so you are just limited by the speed of the connection between the Hue installation and the cluster(s).

    Hi We have configured hadoop on windows environment and wonder if hue can be installed on top of hadoop on windows server

    • Hue Team 1 year ago

      Hue won’t run easily on Windows, we recommend to have it on a Linux machine (but users can access Hue from anywhere, Mac, Linux, Windows, their phone…)

    • k 12 months ago

      Can you please give detailed idea about that ? About how to install hue on windows??

    I have one question regarding logs.
    Can we read job tracker logs from hue logs?

    • Hue Team 1 year ago

      Do you mean the job logs? If yes Hue show all the logs of the Job with MR1/MR2. In practice it pulls them from the Web UI under the cover.

  27. krishna 1 year ago

    As you said,Hue won’t run easily on Windows. I am ready to experiment but couldn’t find anywhere the packages for windows or anything. Is it totally unsupported or difficult to install ? Request you to elaborate

    • Hue Team 1 year ago

      It was never tried, a bunch of packages won’t exist, the Django part is fine though, so overall it should require a bunch of hacking and full security won’t work.

  28. Fred 1 year ago

    Hi all,
    I’ve installed Hue 3.9 version. On the first page in Hue. I can connect with a HUE user (created at first connection but I’ve got this warning (sorry, in French) :
    “hadoop.hdfs_clusters.default.webhdfs_url : Valeur actuelle :
    Echec de la création du fichier temporaire “/tmp/hue_config_validation.15312085668819163275”
    I can create/delete some folders but I can’t write files :
    “Impossible d’effectuer l’opération. Note: you are a Hue admin but not a HDFS superuser, “hadoop” or part of HDFS supergroup, “supergroup”.”
    I’ve followed your tutorial, tried several solutions found on the net. Any result …
    I’m completly lost and would appreciate help
    Thanks in advance

    • Hue Team 1 year ago

      Hello Fred. Can the user that’s running the Hue process write to your HDFS’s ‘/tmp’ directory? Perhaps it doesn’t have permission to write there. Assuming your machine is configured to talk to your hadoop cluster, you could try doing `touch foo && hadoop fs -put foo /tmp/foo`.

  29. Fred 1 year ago

    Thanks for your quick answer. I’ll test your command line tomorrow morning. Anyway, find here some additional informations. The 1rst problem is the system cannot write into /tmp (warning into administation page in my previous mesage). And if I navigate into file system, I cannot write into any directory (if connected with Hue ‘s user for exemple, I cannot write into /user/Hue). One more question before test your command line : Do I test it with Hadoop ‘s user or Hue’s ?
    Once again, thanks for your help.

    • Hue Team 1 year ago

      This would be the operating system user that’s actually executing hue. If you’re using Cloudera CDH, I think this is typically a user named “hue”.

  30. Fred 1 year ago

    Hi Hue team,
    I’ve tested your proposition. For information, I don’t use CDH, I’ve done a “manual installation” of Hue. So, to answer to your question, I can write a “foo” file into HDFS directly from my Debian 8 server using Hue profile. Foo file properties : User : Hue / Group : Supergroup. Maybe a suggestion ?

    • Hue Team 1 year ago

      Can you try from Hue to login with the user ‘hdfs’ ? (If you don’t have an hdfs user on your Hue, create one in the User Admin app)

  31. Fred 1 year ago

    I’ve created a new user “HDFS” from Hue (as superuser) : same error on the administration page and writing a file on HDFS system.
    Maybe something wrong in Hue.ini ? What can I check. Here is an extract from it :

    # Webserver runs as this user
    ## server_user=hue
    ## server_group=hue

    # This should be the Hue admin and proxy user
    ## default_user=hue

    # This should be the hadoop cluster admin
    # default_hdfs_superuser=hdfs

    I’ve tested several cases without success

    • Hue Team 1 year ago

      You need to check the permissions of /tmp on HDFS or your home. You can post the error message when trying to create a file there.

      You should name your user ‘hdfs’, the case is sensitive in linux.

  32. Fred 1 year ago

    Does it mean that I’ve to create a user “hdfs” in Linux, in Hadoop group ?
    Permissions for /tmp : 1777 but keep in mind that I can’t write a file anywhere in the system (/user/hdfs for instance)
    Here is the msg in HUE :
    Impossible d’effectuer l’opération. Note: you are a Hue admin but not a HDFS superuser, “hadoop” or part of HDFS supergroup, “supergroup”.
    I can’t send you the complete msg (HTML format), it seems I’m blocked to access your web site.

    I’ve already test some M/R samples, Flume agents on my cluster. All work fine. I still have to install some other apps (oozie, thrift,…) but I would like to eradicate this error before to continue. No more idea ?

    • Hue Team 1 year ago

      to go back to Hue, have you created the ‘hdfs’ (all lower case) user in Hue itself and try again to login with it in Hue? Which Linux user is running the Hue process btw?

  35. Fred 1 year ago

    Yes I’ve created hdfs’ user in HUE and connected in HUE with. I don’t know what “btw’ means … Anyway, I’ve launched the “./supervisor” command from Linux with alternatively root & hue users. I’ve installed Hadoop with ‘hadoop’ user which belongs to ‘hadoop’ group. I’ve tried to add hue user to hadoop’s group. Yesterday, I’ve executed the ‘`touch foo && hadoop fs -put foo /tmp/foo` test. It walked but when I look at /tmp/foo file’s properties I can see that the file belongs to ‘hue’ user and to ‘supergroup’ group. Too, I’ve tried to add the ‘dfs.permissions.supergroup’ into core-site.xml . Without success. I hope this help. thanks again

    Hi again … May I ask another question ? About HBASE in Hue ? Once Hue worked last week, I tried to use HBASE (Hive was Ok). I received a message which made me think THRIFT was not installed. So I’ve installed it . Installation seems to be OK (thrift -version answers me 0.9.2). But HBASE does not work again. I think the reason is that I can’t launch thrist server. So, I would appreciate (once more) if you could help me or tell me where I could find specific help.

    ./build/env/bin/hue runserver

    by default it works only from localhost, how do I access remotely ? where do I change the address

    • Hue Team 1 year ago


      Note that runserver is intended to be used as the development server. You can make it accessible remotely by passing it the hostname and port, e.g.:
      ./build/env/bin/hue runserver

      But this is not recommended for production, instead you should use the cherrypy server which you should be able to start via:
      ./build/env/bin/hue runcpserver

      or use supervisor

      ./build/env/bin/hue supervisor

      Note: the production server runs on port 8888 and not 8000

    I went through the documentation and found a configuration change that needs to be done as mentioned in below link which assumes HUE is part of the cluster.

    Any idea how will I integrate HUE which is not part of hadoop cluster.

      As long as the Hue machine has the Hue ticket, you will be good, there is not difference with inside or outside the cluster.

    Hi I followed the exact steps as u mentioned. I changes all the configurations in the ini file. But when i open the home page of hue I am getting errors in all the components. please help me. what shoulkd i do? I am using Ubuntu 15.04.

    • Hue Team 1 year ago

      Did you restart Hue? Did you modify the correct ini file? (full path can be seen on /check_config page)

  55. Nikitha 1 year ago

    When i tried to click hive I am getting the following error message in the top right corner.

    Could not connect to localhost:10000 (code THRIFTTRANSPORT): TTransportException(‘Could not connect to localhost:10000’,)

    Please help me.

    • Hue Team 1 year ago

      This means your HiveServer2 is down or Hue is not pointing to the correct host, need to add the host in [beeswax] section of hue.ini

  56. Nikitha 12 months ago


    # Host where HiveServer2 is running.
    # If Kerberos security is enabled, use fully-qualified domain name (FQDN).

    Is this correct?

    I followed the steps for configuration file. But then again i am getting the same error in the hue home page.

    Current value:
    Filesystem root ‘/’ should be owned by ‘hdfs’

    Please help me how to configure the HUE correctly.

    Hello Thank u for your kind reply 🙂 Any how i am not able to completely resolve the configuration error. But even after starting oozie,

    I am getting the following error in the hue home page.

    (unavailable) Oozie Share Lib not installed in default location.

    Can u please help me out.
    I am nit using any packages like Cloudera quick start or hortonworks or anything.

    I have installed all the hadoop components separately and now i ma trying to install and configure hue 3.9 also. And I am going to connect all the hadoop components with HUE.

    Will u help me sir.

    • Hue Team 12 months ago

      This mean you need to install the Oozie Share Lib manually or with CM

      • Nikitha 12 months ago

        Hello I have the oozie-sharelib-oozie-4.1.0.jar
        in the hdfs path as following,

        Does it mean that i already have sharelib installed?
        or do i need to set this particular path in somewhere in pseudo-distributed.ini?

        please tell me sir

        • Hue Team 12 months ago

          If hduser is your oozie user, it looks good. (and oozie has a command to list the sharelib ‘oozie admin -shareliblist’, and Hue will display a warning too)

    • Hue Team 12 months ago

      Looks like HDFS doesn’t have the right permissions… What you can do is to configure Hue to use a different HDFS superuser:

    • Hue Team 12 months ago

      You are probably not configuring the correct hue.ini, please check that you are editing the correct file path like detailed in the post

      • Tao 11 months ago

        I’ve exactly same issue with soniya, but I’ve fixed first two issues. For the rest, i still don’t know how to fix it. Especially for “Oozie Editor/Dashboard The app won’t work without a running Oozie server “, I’ve opened ooozie server manually in terminal and it’s working perfectly. My file directory is /usr/local/hadoop/hue/desktop/conf/pseudo-distributed.ini, and I’ve uncomment oozie_url=http://localhost:11000/oozie. But it still said the server is not running. So can you give me some hints to fix this problem?

        • Hue Team 11 months ago

          On the /desktop/dump_config page of Hue, liboozie tab, what do you see for the server?

          How about using the real hostname instead of localhost?

    What can I do now, I tried to login as hdfs, in that account also I cannot use access File Browser.

    When i try to use sqoop in Hue, i got this error,
    Sqoop error: Could not get connectors.
    How can i solve it?

  70. Sayle Matthews 10 months ago

    I have installed hue in my user directory on a Google DataProc cluster and opened up port 8000 on the firewall. Note I have not changed any config files at all for this. This was building from source.

    I try to connect but am getting a connection refused error going to http://my_ip:8000/ in Chrome.

    Tried hitting http://my_ip:8000/desktop/dump_config with the same results as well.

    I also changed the config file at desktop/conf/pseudo-distributed.ini to be on a different port and restarted it, but the message still says 8000. So I suspect it is not using that config file.

    Any thoughts on this?

    • Hue Team 10 months ago

      Hi! So, to check if the port 8000 really works, you can try to run this from any folder

      python -m SimpleHTTPServer 8000

      and you should be able to see its content.
      Then: how do you start Hue? Can you try with this?

      ./build/env/bin/hue runserver_plus <-- here you can change the port

      • Sayle Matthews 10 months ago


        The simple HTTP server thing worked and gave me a 404 error, but that at least shows it wasn’t being blocked by something else on the machine hitting that port.

        I ran it on the port 8888 with that command, changed the firewall rule, and it is working now. So I am not really sure why that’s the case honestly.

        • Hue Team 10 months ago

          Glad to hear! Can it be there’s something else running on 8000?

    Hi Hue Team,
    i’d like Hive queries come on Yarn as Hue’s user. I tried these parameters:

    hive.server2.enable.doAs=true (hive-site.xml)

    But impersonation doesn’t work yet. Could you please help me?

    • Hue Team 8 months ago

      If you want to disable impersonation, you should changed ‘true’ to ‘false’.

  77. Alex 8 months ago

    In according with Hive documentation ( “By default HiveServer2 performs the query processing as the user who submitted the query. But if the following parameter is set to false, the query will run as the user that the hiveserver2 process runs as.

    hive.server2.enable.doAs – Impersonate the connected user, default true.”

    However I tried with that parameter setted to false also, but Beeswax executes the queries as “hive” user yet.
    Please help me…i need to track queries launched by users for auditing purposes.

      You need to set it to true if you want to have the queries submitted by the real user and not ‘hive’

          The sample popup can indeed freeze until the data is there. This is fixed in Hue 3.12 and will get even friendlier in 3.13.
