stack commented on HBASE-1667:
------------------------------
HBaseAdmin now has a stopMaster which stops the master only. Need to get this
out to shell or into bash scripts.
> hbase-daemon.sh stop master should only stop the master, not the cluster

> Key: HBASE-1667
> URL: https://issues.apache.org/jira/browse/HBASE-1667
> Project: HBase
> Issue Type: Improvement
> Components: master, scripts
> Affects Versions: 0.20.0
> Reporter: Rong-En Fan
> Fix For: 0.92.0
>
>
> 0.20 supports multi masters. However,
> bin/hbase-daemon.sh stop master
> on backup masters will bring the whole cluster down.
> Per rolling upgrade wiki that stack pointed out, kill -9 for backup master is
> the only way to go currently.
> I think it's better to make some sort of magic that we can use something like
> bin/hbase-daemon.sh stop master
> to properly stop either the backup master or the whole cluster.
