Jonathan Hsieh resolved HBASE-6960.
-----------------------------------
Resolution: Duplicate
> Support fast and graceful master failover
> -----------------------------------------
>
> Key: HBASE-6960
> URL: https://issues.apache.org/jira/browse/HBASE-6960
> Project: HBase
> Issue Type: Bug
> Components: master
> Affects Versions: 0.94.2, 0.95.2
> Reporter: Jonathan Hsieh
>
> If you have multiple masters, you should be able to kill the primary and have
> the backups assume control within seconds instead of having to wait the
> default 3mins before an ephemeral znode expires.
> The expected behavior is similar to how region servers when killed (not -9)
> trigger the servers shutdown handler and quickly pass of its regions for
> reassignment. In this case, a master that is killed is removes the znode and
> allow another to become the primary. A related follow on feature could be
> the ability to failover to another primary without taking the orignal primary
> down.
