Configuring secure access between Solr and Cloudera Data Explorer (Hue)

If you are using Solr (search) to build dynamic search dashboards and explore data from the Data Explorer web UI, and have secured your Cloudera cluster using Kerberos, then you must enable secure access between the Solr service and Data Explorer by turning on the security_enabled parameter in the hue_safety_valve.ini file.

The security_enabled parameter is set to false, by default. To enable secure access between Solr and Data Explorer:

  1. Sign in to Cloudera Manager as an Administrator.
  2. Go to Clusters > Hue service > Configuration and search for the Hue Service Advanced Configuration Snippet (Safety Valve) for hue_safety_valve.ini field.
  3. Go to the [search] section and set the value of the security_enabled parameter to true, as shown in the following sample: 
    [search]
# Requires FQDN in solr_url if enabled
security_enabled=true
# URL of the Solr Server
solr_url=http://[***FQDN-SOLR-HOST***]:8983/solr
  4. Click Save Changes.
  5. Restart the Hue service.
