Search is a great way to interactively explore your data. The Search App is continuously improving and now comes with a better support for real time!
In this video, we are collecting tweets with Spark Streaming and directly indexing them into Solr with the Spark Solr app. Note that we are using a slightly modified version that adds more tweet information.
You can see the tweets rolling in! Compared to the previous version:
- the dashboard updates its widgets only when the data changes without any page jumping
- the dashboard can refresh itself automatically every N seconds
- a main date filter lets you quickly select a rolling date range for all the dashboard
Tweets coming in
Instructions
Download a nightly Solr 5.x, uncompress it and start it:
bin/solr start -cloud bin/solr create -c tweets
Then compile the Spark Solr app.
Enable the analytic widgets in hue.ini:
[search] latest=true
Sum-up
They are other ways to index data in near real time but we took this approach as the scenario was working out of the box with just Spark Streaming and the Solr app. Next time, we will preview the new Analytics Features of Solr 5.2 and show how we can use Python Spark to index some data!
As usual feel free to comment on the hue-user list or @gethue!

Hello Hue Team,
I’m trying to work through this tutorial but I’m running into a few issues.
When I click the drop-down to select a search index, I don’t see tweets_shard1_replica1. However, if I check the box for Show cores, I do see one called twitter_demo_shard1_replica1. But, that dataset only has 16 fields compared to the 42 in the demo, and the field ‘hashtags’ is not included. Also, the global time filter does not appear when I select this dataset. Do I need to install this dataset? I did install all application examples from step 2 of the Hue Quick Start Wizard.
I’m using Hue 3.7.0 from the quickstart v. 5.4.0 VMware vm.
Thanks,
Blair-
The global time filter is in Hue 3.9 which is not released yet, but you should not need it.
If you are seeing only 16 fields, this is probably because not all the dynamic fields were fetch when you opened the dashboard. Could you just reload the page?
-
I tried a few things to get the dynamic fields to appear, but was not successful. I tried page reload, create a new dashboard, re-install the application examples, and delete and re-import the VM from the download zip file. Also, the counter button does not exist in my version.
Thanks,
Blair-
Yes, counters are coming in Hue 3.9 which is not released but are in master.
When you click on a result row, do you see some dynamic fields value there?

Hello there,
We’re trying to create a dynamic dashboard using the Solr Search using a file to load some information and make hue read and create the graphics. But the panel that we are using is not refreshing even checking the checkbox of AutoRefreshing. The values from index still static…
Is there something that we didn’t noticed?
Thanks

I just checked on http://demo.gethue.com/search/?collection=14 and it works if you check and uncheck the box after picking the time.
-
Sorry. When I wrote that message I forgot to mention that we are trying to add some values into an index created. In that demo has something like that?
-
Yes, don’t you see in the video the new tweets coming in?
-
Yes but when we run our application in spark updating a file that was being used by the index, the workbook didn’t updated the charts and the tables. Could you release the spark code to us? Thanks
-
The spark code is listed already: https://github.com/romainr/spark-solr
What you might miss is what we do at 3:50 in the video to trigger the automatic refresh of the dashboard.

Hello, How to use Metrics in HUE Dashboards, I want to create bar chart with Y-Axis using Sum not Count as usual
-
You can turn the analytics on with https://github.com/cloudera/hue/blob/master/desktop/conf.dist/hue.ini#L1120
And full support of Solr 6 will come next year with https://issues.cloudera.org/browse/HUE-5116 is finished

Will Ubuntu 16.04 support Hue?
-
I just tried and a freshly installed 16.04 supports Hue. The steps I did:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installersudo apt-get install ant gcc g++ libffi-dev libkrb5-dev libmysqlclient-dev libsasl2-dev libsasl2-modules-gssapi-mit libsqlite3-dev libssl-dev libxml2-dev libxslt-dev make maven libldap2-dev python-dev python-setuptools libgmp3-dev libz-dev
git clone https://github.com/cloudera/hue.git
cd hue
make apps
build/env/bin/hue runserver

Hi All,
I use HUE 3.11. Everythings seem work fine buidind Dashboard. But I can’t see global time filter to auto refresh indexes. I looked for a parameter in hue.ini but
I don’t find it. Could you help me please ?-
Hi, you will need to have at least one field defined as date/time in your Solr collection to enable that feature
-
-
Thanks for your very fast answer. I allready have a date/time field in my Solr collection :
ex :
But I cannot see the option to schedule collection’s auto-refresh (every 5mn, 10mn, …) -
Sorry my sample disappeared when I validated my post
field name=”PRE_DATE_EXPED” type=”tdates”-
We currently don’t list ‘tdates’ as dates, only ‘tdate’. Would adding it there work for you?
-
-
Thanks but … I tried your solution creating a new collection with “tdate” type fields. Any changes. Maybe I ‘m not clear. I ‘d just like to automatically refresh Dashboard after new data injection. But I can’t see “time panel” on top of HUE Search screen, (near from collection name). I’ve seen some demo & video where it can be done automatically and in which the user could change refresh Schedule. To be complete I use HUE 3.11 & Solr 6.4.1. Thanks again.
-
If you use Hue 3.11, tdate should be recognized and will enable the date filtering.
https://github.com/cloudera/hue/blob/release-3.11.0/apps/search/src/search/static/search/js/search.ko.js#L1248Would you send a mini csv of a few rows of data and I could try to plot it too?
-
-
Please find a sample of my data. but once again, I just want to access at “time panel” to automatically refresh my collection, not to enable the date filtering.

So I am using master Hue and I see the time panel. If you left the filter selected with Rolling/’All’ it should not apply any time filtering (and you can check the live update)
