> Someone made mention of this loop last week but I don't think I filed an =
issue.  Here is another instance, again from a secret hbase admirer:
> "It seems that when Zookeeper dies and restarts, all client applications =
need to be restarted too. I just restarted HBase in non-distributed mode (w=
hich includes a ZK) and now my application can't reconnect to ZK unless I r=
estart it too.  I'm stuck in this loop:
> {code}
> 2010-07-19 00:13:05,725 INFO org.apache.zookeeper.server.NIOServerCnxn:
>   Closed socket connection for client /127.0.0.1:55153 (no session establ=
ished for client)
