             Summary: Fix bug in reading the ephemeral processor nodes from zookeeper.
                 Key: SAMZA-1607
                 URL: https://issues.apache.org/jira/browse/SAMZA-1607
             Project: Samza
          Issue Type: Bug
            Reporter: Shanthoosh Venkataraman
            Assignee: Shanthoosh Venkataraman


Existing implementation of reading the data of ephemeral processor nodes in zookeeper happens in two steps.

   A. Fetch the list of ephemeral processor nodes.

   B. Read the data of each processor node from the list.

 

Some zookeeper nodes present in step A might be unavailable in the step B. This exception in unhandled currently and can kill the leader processor unnecessarily.
