Subject [jira] Updated: (HBASE-1667) hbase-daemon.sh stop master should only stop the master, not the cluster
Date Tue, 09 Mar 2010 18:13:27 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1667?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jean-Daniel Cryans updated HBASE-1667:
--------------------------------------

    Summary: hbase-daemon.sh stop master should only stop the master, not the cluster  (was:
hbase-daemon.sh stop master for standby masters should not stop the whole cluster)

Changing the title to reflect a broader scope, stop master should only stop the master, not
the cluster.

>             Project: Hadoop HBase
>          Issue Type: Improvement
>          Components: master, scripts
>    Affects Versions: 0.20.0
>            Reporter: Rong-En Fan
>             Fix For: 0.21.0

>
> 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.
