job.setNumBspTask()
[ https://issues.apache.org/jira/browse/HAMA-379?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Thomas Jungblut updated HAMA-379:
---------------------------------
Attachment: hama-379-v2.patch
updated this to work with current trunk, updated the localbsprunner to return the real amount of available trackers (num of processor cores) to avoid log warnings.

> 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.
