> Add peak memory usage counter for each task

> Key: MAPREDUCE-4710
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4710
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Components: task
> Affects Versions: 1.0.2
> Reporter: Cindy Li
> Assignee: Cindy Li
> Priority: Minor
> Attachments: MAPREDUCE-4710-trunk.patch, mapreduce-4710-v1.0.2.patch,
> mapreduce-4710.patch, mapreduce4710-v3.patch, mapreduce4710-v6.patch,

>
> 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.
