I think now I can explain the session expirations; hbase cilents especially
up in a map/reduce task can exit without closing the zk session. Will fix.

Yes, right, that's what I meant to say - what is causing the client to
"die", throwing read error on the server side, and then later you end up
with the session expiration because the client was not closed gracefully.

That should be the case since the server gets an exception reading from the
socket - meaning the client went away (not gracefully) and that leads the
server to expire the session in 30 seconds.

Oops too late. ;-)
I'm perplexed as to why you see all these expirations though. Are you
killing your clients, ie not cleaning up the ZK session gracefully via
close()?

No, it's unrelated. Notice that the 00790 only shows up once.
It's a co-incidence that the other sessions are all expiring.
also notice that 0x1250f26319f0
Please disregard. Sorry for the noise (Patrick, of note, I am seeing this
session timeout on a cluster other than Zhenyus).
