jamjae kim commented on HBASE-17885:
------------------------------------
I try it again.
(branch-1 and git apply)
many deletion, and reverse scan.
then, i can see "Finished memstore flush of ~...."
memstore is safely running.
but, reverse scan still timeout, i think that cause so many deletion.
and region server still running ReverseScan( jstack )

Can I (Hbase client) know that server's running status?
How to stop that thread(RpcServer.default.FPBQ.Fifo.handler=29)??
possible?
