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

             Summary: Check Existence of Zookeeper Recovery Node Before Reading It.
                 Key: ACCUMULO-635
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-635
             Project: Accumulo
          Issue Type: Bug
            Reporter: David Medinets
            Assignee: David Medinets
            Priority: Minor


I don't know why but my errors have started to display the following message. I tracked down
the source. Basically the Zookeeper node is being read without first making sure that it exists.

{code}
