Date Fri, 13 May 2011 01:07:47 GMT
Add task ID and superstep count informations to lock file
---------------------------------------------------------

                 Key: HAMA-387
                 URL: https://issues.apache.org/jira/browse/HAMA-387
             Project: Hama
          Issue Type: Improvement
          Components: bsp
    Affects Versions: 0.2.0
            Reporter: Edward J. Yoon
             Fix For: 0.3.0


I think, the lock file must include:

 * the job ID
 * the task ID of the lock file owner
 * the current superstep count

to check ownership and validation.

Currently they are named by hostname, but multi-tasks can be run per one groomserver in the
future.
