Lars Hofhansl commented on HBASE-7865:
--------------------------------------
I had the same thought, but HBASE-7728 was checked in before I cut RC0, so
presumably that was included.
That said, though, the line numbers do not quite match up, and as Ted mentioned
the last change to HLog.java was HBASE-7728. So something is a bit strange.
Looking at the stack trace, this seems different from HBASE-7728. Something
else already holds the cacheFlushLock, which implies that another thread tried
to flush and never finished (but I cannot see that thread in the jstack).

> 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.
