Subject Re: coould anyone tell me why this zookeeper Exception happens?
Date Mon, 28 Jun 2010 00:10:25 GMT
When a zk client closes its session it sends a close session request to 
the server. In some cases the client may not finalize it's side of the 
close before the server closes the session - including closing the 
socket. If this happens the client may output this message (read rc of 
-1 means "end of stream"). Nothing to worry about in this context.
