stack updated HBASE-1999:
-------------------------
Attachment: hcm.patch
This patch seems to do the right thing. I tried it in a MR context and I see
closeSession instead of expiredSession in zk logs when its in place. Task logs
look fine too.
> When HTable goes away, close zk session in shutdown hook or something...

> Currently, while there is a close on HTable, it does not let go of the zk
> session.. it does not call close... because the session is shared by all
> HTables in the VM. Add a shutdown hook that will close zk on the way out.
> Otherwise it makes for session timeouts in zk server logs.
