Jean-Marc Spaggiari updated HBASE-7865:
---------------------------------------

    Attachment: hbase-root-master-hbasetest.out.4

I found that.

Might be related.

What I'm doing is that I'm running 10 times a loop to "rm -rf hbase data; start-hbase; PerformanceTest; stop-hbase". And on this iteration I got issues. all others went well.

It's 10 loops per hbase-0.94 version. Which mean 60 loops in total.

> 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.
