[jira] [Created] (SAMZA-666) Add checksum to OFFSET file to validate against any data corruption

Navina Ramesh created SAMZA-666:
-----------------------------------

             Summary: Add checksum to OFFSET file to validate against any data corruption
                 Key: SAMZA-666
                 URL: https://issues.apache.org/jira/browse/SAMZA-666
             Project: Samza
          Issue Type: Task
            Reporter: Navina Ramesh
            Assignee: Navina Ramesh


We are using the offset stored in a file to restore the state. If the file is corrupt, then we may rebuild a partial/incorrect state. 

Hence, we need to store checksum in the offset file to make sure we don't read and act on a corrupted value
