[jira] [Created] (SAMZA-1382) Support for ZK communication version protocol.

Boris Shkolnik created SAMZA-1382:
-------------------------------------

             Summary: Support for ZK communication version protocol.
                 Key: SAMZA-1382
                 URL: https://issues.apache.org/jira/browse/SAMZA-1382
             Project: Samza
          Issue Type: Bug
            Reporter: Boris Shkolnik


Introducing a ZK communication version protocol will allow us in the future to detect incompatible versions of participants at the start of the job and stop them right away.

In this case we can allow participants of different build version, but same communication protocol version to work together.

One option would be to write the protocol version as a data of the root zk node of each job.
