> 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.
