> Project: Apache Knox
> Issue Type: New Feature
> Components: Server
> Affects Versions: 0.12.0, 0.13.0
> Reporter: Rick Kellogg

>
> Provide high-availability/fail-over between Knox and SOLR/HBase/Kafka 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.
