We are running cdh3u1 on centos 5.6 and we have frequent problems shutting

them is a kill -9 which is a little harsh. I tried doing a normal jstack
but it doesn't respond. With the -F option I get what you see at the bottom
of the email. Also in the region server logs I see the following which
would imply that it should be shutdown.
