Subject [jira] [Created] (HAMA-379) Setting default values to job.setNumBspTask()
Date Mon, 18 Apr 2011 09:25:05 GMT
Setting default values to job.setNumBspTask()
---------------------------------------------

                 Key: HAMA-379
                 URL: https://issues.apache.org/jira/browse/HAMA-379
             Project: Hama
          Issue Type: Task
          Components: bsp
    Affects Versions: 0.2.0
         Environment: linux
            Reporter: Thomas Jungblut
            Priority: Minor
             Fix For: 0.3.0


When a user does not explicitly sets the number of BSP tasks in his own jobs the job will
hang forever with this output:


    11/04/17 20:07:50 INFO bsp.BSPJobClient: Running job: job_201104172007_0001
    11/04/17 20:07:53 INFO bsp.BSPJobClient: Current supersteps number: 0


We should provide a check that will reject wrong values: 1 > numOfTasks > numberOfGrooms
(is this upper bound right or can multiple tasks of the same job run on the same groom?)

This could be implemented in the method "submitJobInternal" of the BSPJobClient. We should
add an info log statement if we changed the value.
