Subject [jira] [Commented] (HBASE-7865) HBase regionserver never stops when running `bin/stop-hbase.sh` on master
Date Thu, 21 Feb 2013 14:34:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7865?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13583224#comment-13583224
] 

Jean-Marc Spaggiari commented on HBASE-7865:
--------------------------------------------

Now that servers are killed automatically after 1200s, it will be very difficult to capture
those stacks anymore. Maybe we should add a jstack capture before doing the kill -9 in the
stop script, so we can keep a track of what's going on when it's failing? I don't have any
issue close this JIRA.

> I faced 3 regions (out of 8) never stopping today. This is pretty bad because the script
is supposed to wait until all the RS stopped to re-start everything, therefor, servers are
never going back online.
> HBASE-7838 will help with that and will kill the RSs. But that will not really solve
the root cause.
> Attached are the jstack for the 3 servers.
