[jira] [Created] (SAMZA-354) Write tool to convert old-style checkpoint log to post-SAMZA-123 format

Jakob Homan created SAMZA-354:
---------------------------------

             Summary: Write tool to convert old-style checkpoint log to post-SAMZA-123 format
                 Key: SAMZA-354
                 URL: https://issues.apache.org/jira/browse/SAMZA-354
             Project: Samza
          Issue Type: Task
    Affects Versions: 0.8.0
            Reporter: Jakob Homan


After SAMZA-123, the checkpoint log has a new format (keyed entries interspersed with statelog-partition mapping) and a new name.  It would be simple to write a tool that would consume an old-style log and write out a new-style log, using the GroupByPartition strategy.  This would allow existing jobs to not lose checkpointing.
