             Summary: Reading ephemeral node data throws 
                 Key: SAMZA-1583
             Project: Samza
          Issue Type: Bug
            Reporter: Shanthoosh Venkataraman
            Assignee: Shanthoosh Venkataraman

Reading the processorId's of zookeeper ephemeral nodes are of following form:

A. ephemeralZkNodes = Get the list of ephemeral zookeeper nodes.

B. For each zkNode in ephemeralZkNodes:
          fetch data of the zkNode.

The zkNodes returned by the operation A, may no longer be available when fetch 
data remote call was made. This will cause zkClient to throw 
ZkNoNodeExistsException. This exception is unhandled currently, there by 
failing the leader.
