> Project: Hadoop Map/Reduce
> Issue Type: New Feature

> Each task has counters PHYSICAL_MEMORY_BYTES and VIRTUAL_MEMORY_BYTES, which
> are snapshots of memory usage of that task. They are not sufficient for users
> to understand peak memory usage by that task, e.g. in order to diagnose task
> failures, tune job parameters or change application design. This new feature
> will add two more counters for each task: PHYSICAL_MEMORY_BYTES_MAX and
> VIRTUAL_MEMORY_BYTES_MAX.
