[Hadoop-common-dev] Getting the cpu, memory usage of map/reduce tasks

Hi -- Is it possible to get the cpu and memory usage of individual
map/reduces tasks when any mapreduce job is run.
I came across this jira issue, but was not sure about the exact ways to
access in the current hadoop distriubtion
https://issues.apache.org/jira/browse/MAPREDUCE-220

Any help is highly appreciated.

Thanks,
Bikash
