Sumit Gupta commented on KNOX-567:
----------------------------------
[~tanping], you are right, the refactored HA dispatcher is available for all
services but as usual you can extend that functionality to provide any special
handling that is needed for a particular service. Hive is such a case for us
(to be specific it is HiveServer2 HA). To answer your question specifically, I
have successfully tested the default HA behavior for HBase, HCat and Oozie. The
extended support for HS2 also works and involves some zookeeper configuration.
The docs for all this can be found here:

> Having Knox Supporting Hadoop/Yarn/HBase/Hive High Availability
> ----------------------------------------------------------------
>
> Key: KNOX-567
> URL: https://issues.apache.org/jira/browse/KNOX-567
> Project: Apache Knox
> Issue Type: New Feature
> Components: Server
> Affects Versions: 0.7.0
> Reporter: Tanping Wang
>
> Currently Knox only provides limited support of high availability to the
> Hadoop ecosystem, i.e. Knox supports only high availability for webHDFS. We
> need to make Knox supports Yarn, HDFS, Hive and HBase high availability as
> well. Especially after Knox supports Hadoop ecosystem UIs, having Knox
> supports at least the HA mode of Hadoop, Hive and HBase becomes even more
> critical.
