             Summary: Checkpoint log and state log should resize partition count upward if necessary at job start
                 Key: SAMZA-330
                 URL: https://issues.apache.org/jira/browse/SAMZA-330
             Project: Samza
          Issue Type: Improvement
            Reporter: Jakob Homan


Currently if a the checkpoint log or state log partition count increases on job restart due to the inclusion of new streams with a higher partition count, the corresponding Kafka topics are increased to accommodate this change.  In the case of the the checkpoint log, we will get a job failure at startup.  We should compare the current partition size with the required and size upward if necessary at job start.
