BSPTask should periodically ping its parent.
--------------------------------------------

                 Key: HAMA-498
                 URL: https://issues.apache.org/jira/browse/HAMA-498
             Project: Hama
          Issue Type: Improvement
          Components: bsp
    Affects Versions: 0.4.0
            Reporter: Edward J. Yoon
             Fix For: 0.5.0


As described in http://wiki.apache.org/hama/GroomServerFaultTolerance
BSPTask should periodically ping its parent 'GroomServer' for their health status.

1. If Tasks are unable to ping their parent 'GroomServer', it should be killed themselves.
2. And, if GroomServer does not receive ping from the childs, GroomServer should check whether
that child is running.

You don't need to implement recovery logic in this issue.
