Subject [jira] [Commented] (HBASE-5213) "hbase master stop" does not bring down backup masters
Date Fri, 06 Apr 2012 15:19:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13248416#comment-13248416

David S. Wang commented on HBASE-5213:
--------------------------------------

Greg is out of town for the next week or so ... IMHO if it's breaking 0.90, we should revert
for now and Greg can look at it when he gets back.

> Typing "hbase master stop" produces the following message:
> "stop   Start cluster shutdown; Master signals RegionServer shutdown"
> It seems like backup masters should be considered part of the cluster, but they are not
brought down by "hbase master stop".
> "stop-hbase.sh" does correctly bring down the backup masters.
> The same behavior is observed when a client app makes use of the client API HBaseAdmin.shutdown()
http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/HBaseAdmin.html#shutdown()
-- this isn't too surprising since I think "hbase master stop" just calls this API.
> It seems like HBASE-1448 address this; perhaps there was a regression?
