Amar Kamat commented on MAPREDUCE-2469:
---------------------------------------

The testcase failure (Test#7, Archive: Deleting a file in archive) and the findbugs failures
are not related to this patch.

> Currently, the task counters report VSS and RSS usage of the task. The task counter should
also report the total heap usage of the task also. The task might be configured with a max
heap size of M but the task's total heap usage might only be H, where H < M. In such a
case, knowing only M doesn't provide a complete picture of the task's memory usage.
