> Key: HIVE-18982
> URL: https://issues.apache.org/jira/browse/HIVE-18982
> Project: Hive
> Issue Type: Sub-task
> Components: HiveServer2
> Affects Versions: 3.0.0
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
> Priority: Major
> Attachments: HIVE-18982.1.patch, HIVE-18982.2.patch
>
>
> HIVE-18281 added active-passive HA. There might be a administrative need to
> trigger a manual failover of HS2 Active server. Add command line tool to view
> list of all HS2 instances and trigger manual failover (only under force
> mode). The clients currently connected to active HS2 will be closed. In
> future, more options to existing clients connections can be handled via
> configs/options (like wait until timeout, wait until current sessions are
> closed etc.)
