Subject [jira] [Commented] (HBASE-7865) HBase regionserver never stops when running `bin/stop-hbase.sh` on master

Lars Hofhansl commented on HBASE-7865:
--------------------------------------

Thank JM. And thanks for the jstacks.

>From the line-numbers I am pretty sure that you have a version of HBase deployed that
does not have HBASE-7728 (Which is what Ted was also pointing out above).

bq. Why are there still non-daemon region open threads running?
Turns out this is unrelated. The services will be shut down after all regions are closed (which
does not happen in this case).

> 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.
