Troubleshooting: Cloudera Hue not able to access Solr collections through Search tab assuming both are set up with CDH4.

Solution

a. Open hue.ini file that you are using and check if Solr URL is correctly mentioned there or not.

  1. Go to its configuration UI page (http://localhost:8888/dump_config) and check the configuration for search.
    /etc/hue/hue.ini configuration

    Configuration Sections and Variables solr_url
  2. Make sure /etc/hue/hue.ini file must have URL of the Solr Server
    solr_url=http://<solr server name>:8983/solr/

b. Go to the file /etc/default/solr and check whether you have below section uncommented

SOLR_SECURITY_ALLOWED_PROXYUSERS=hue
SOLR_SECURITY_PROXYUSER_hue_HOSTS=*
SOLR_SECURITY_PROXYUSER_hue_GROUPS=*

This allows hue user to access solr collections as proxy users.

c. Check if solr service is running. If you have made any change you can restart both the services to be on safer side

sudo service solr-server status

sudo service solr-server restart
sudo service hue restart

Then if you click on the search button you should be able to see all your solr collections ready to be imported.
Import Collections and Cores
