[jira] [Created] (MAPREDUCE-4263) Use taskkill /T to terminate tasks on Windows

Bikas Saha created MAPREDUCE-4263:
-------------------------------------

             Summary: Use taskkill /T to terminate tasks on Windows
                 Key: MAPREDUCE-4263
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4263
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 1.0.0
            Reporter: Bikas Saha


On Linux setsid is used to link the processes spawned by the tasks into the same session. So termination of the task terminates the entire tree. We need to do the same for Windows. This is not fool proof but should be sufficient until we have a potentially better solution in MAPREDUCE-4260.
