Subject Re: Instructions on setting 'ConnectionTimeout'
Date Mon, 08 Jul 2013 15:33:45 GMT
In ZooKeeper, you must wait for SysConnected before making any API method calls. Curator handles
this internally. The connection timeout defines how long Curator will wait for the SysConnected
before throwing ConnectionLossException.

I hope this helps.
