Subject [jira] [Commented] (HBASE-7865) HBase regionserver never stops when running `bin/stop-hbase.sh` on master
Date Sat, 16 Feb 2013 14:59:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7865?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13579802#comment-13579802

Jean-Marc Spaggiari commented on HBASE-7865:

bq. HDFS was still up & running? All the computers were still there as well?
Yes. I'm not touching HDFS. I can still see all the nodes live in the Hadoop UI.

bq. What do you exactly to stop the cluster?
Nothing more. It stopped 5 RS. It's sometime stopping all of them, not always. Then to stop
the remaining, I have a ssh loop with a killall -9 java.

bq. What are the versions of HBase & HDFS?
HBase is 0.94.5RC0. I have downloaded it yesterday from the source, and built it. So it should
be the same as 0.94.5 I think.

bq. Do you have the logs (region server / master / datanode)?
Unfortunatly I have restarted the instances and cleared the logs :( I will keep them if I'm
facing this again.

> 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.
