[jira] [Created] (KNOX-1041) High Availability Support For Apache SOLR

Rick Kellogg created KNOX-1041:
----------------------------------

             Summary: High Availability Support For Apache SOLR
                 Key: KNOX-1041
                 URL: https://issues.apache.org/jira/browse/KNOX-1041
             Project: Apache Knox
          Issue Type: New Feature
          Components: Server
    Affects Versions: 0.12.0, 0.13.0
            Reporter: Rick Kellogg
            Assignee: Rick Kellogg


Provide high-availability/fail-over between Knox and SOLR using the existing DefaultHaDispatch mechanism and a customized URLManager implementation with knowledge of active hosts in Zookeeper.

When SOLR Cloud is used the active hosts are stored in Zookeeper under the /live_nodes path.  The attached custom URLManager implementation queries Zookeeper for the active hosts upon startup.  In the event of fail-over, it updates the internal list of hosts.

The HS2ZookeeperURLManager implementation used to provide similar functionality for Hive was used as a starting point.
