    Description

      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.
