Hue now defaults to using Yarn since version 3.
First, it is a bit simpler to configure Hue with MR2 than in MR1 as Hue does not need to use the Job Tracker plugin since Yarn provides a REST API. Yarn is also going to provide an equivalent of Job Tracker HA with YARN-149.
Here is how to configure the clusters in hue.ini. Mainly, if you are using a pseudo distributed cluster it will work by default. If not, you will just need to update all the localhost to the hostnames of the Resource Manager and History Server:
[hadoop]
...
\# Configuration for YARN (MR2)
\# ------------------------
[[yarn_clusters]]
[[[default]]]
\# Enter the host on which you are running the ResourceManager
resourcemanager_host=localhost
\# The port where the ResourceManager IPC listens on
resourcemanager_port=8032
\# Whether to submit jobs to this cluster
submit_to=True
\# URL of the ResourceManager API
resourcemanager_api_url=http://localhost:8088
\# URL of the ProxyServer API
proxy_api_url=http://localhost:8088
\# URL of the HistoryServer API
history_server_api_url=http://localhost:19888
\# Configuration for MapReduce (MR1)
\# ------------------------
[[mapred_clusters]]
[[[default]]]
\# Whether to submit jobs to this cluster
submit_to=False
And that’s it! You can now look at jobs in Job Browser, get logs and submit jobs to Yarn!
