This is the documentation for Cloudera Manager 5.1.1.
Documentation for other versions is available at Cloudera Documentation.

Installing Search

Cloudera Search is provided by the Solr service. The Solr service is included with CDH 5. To use Cloudera Search with CDH 4, you must install both CDH and Search on the hosts that will run Search.
  Note:

Installing Search after Upgrading Cloudera Manager

If you have just upgraded Cloudera Manager from a version that did not support Search, the Search software is not installed automatically. (Upgrading Cloudera Manager does not automatically upgrade CDH or other managed services). You can add Search using parcels; go to the Hosts tab, and select the Parcels tab. You should see at least one Solr parcel available for download. See Parcels for detailed instructions on using parcels to install or upgrade Solr. If you do not see any Solr parcels available, click the Edit Settings button on the Parcels page to go to the Parcel configuration settings and verify that the Search parcel repo URL (http://archive.cloudera.com/search/parcels/latest/) has been configured in the Parcels configuration page. See Parcel Configuration Settings for more details.

Post Installation Configuration

See The Solr Service in Managing Clusters with Cloudera Manager for instructions on configuring Cloudera Search.
