Edit: This post is deprecated since Hue 3.6, clicking on the install button is the only thing to do now!

Hue comes up with a series of examples (for Hive/Impala, HBase…) to help you get started with Hadoop. Recently, some demo Collection/Indexes were added for the Search Application:

To install them,  got to Hue on the /about/ page and on Step 2 click on ‘Solr Search’:

This will install the search templates in Hue. To make the demo work by default, Hue is using a predefined Solr response. Hue displays a warning in this case as the page is not updated when typing a query:

The next step is to create the indexed into Solr. First, make sure that Solr has been setup and initialized correctly.

In order to query a live dataset, you need to index some data. Go on the Hue machine:



cd $HUE_HOME

cd apps/search/examples/bin

Then create the Solr collections:

./create_collections.sh

In case Solr is not on the same machine, add this parameter in the script:

-solr http://localhost:8983/solr

Then index some example data with:

./post.sh

Same, if Solr is on a different machine, update the url:

URL=http://localhost:8983/solr

And that’s it! The above warning message will disappear and you will be able to query Solr indexes in live!

Then go create your own Search!
