So I said I'd tell you if the problem came up again, so here's the error that
gets thrown at me over and over again:
09/10/02 23:59:23 WARN zookeeper.ClientCnxn: Exception closing session 0x0 to

This is actually different from what it was the other day. Any clue what's
going on here?

Subject: Re: NoNode Exception?
Care to show us your configuration? Are you managing the zookeeper
ensemble yourself or do you let HBase do it?
Can I see a full stack trace along with some lines before and after?
Try to get the first one, when things go awry.
