--------------------------------------

             Summary: Failure when znode is removed before we can read its 
contents.
                 Key: MESOS-1392
                 URL: https://issues.apache.org/jira/browse/MESOS-1392

Looks like the following can occur when a znode goes away right before we can 
read it's contents:
