             Summary: Reading ephemeral node data throws ZkNoNodeExistsException.
                 Key: SAMZA-1583
                 URL: https://issues.apache.org/jira/browse/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.
