Jean-Marc Spaggiari commented on HBASE-7865:
--------------------------------------------
I just faced it again with 0.94.5.
I looked at 0.94.5RC1 tag and also in the 0.94 branch and I did not found the
modifications.
http://svn.apache.org/viewvc/hbase/tags/0.94.5RC1/src/main/java/org/apache/hadoop/hbase/regionserver/wal/HLog.java?revision=1443844&view=markup
http://svn.apache.org/viewvc/hbase/branches/0.94/src/main/java/org/apache/hadoop/hbase/regionserver/wal/HLog.java?view=markup
Based on the patch for HBASE-7728 there should be something like "this.writer =
null;" close to line 1010 in HLog and it's not there.
I will apply this patch manually locally and re-deploy with a customed 0.94.5
version...

> 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.
