----------------------------------

    Attachment: HADOOP-5738-2.1.patch

Sorry, my comments were unclear. I mean only that v2 should be committed to 0.21 (with the
typo fix) and anyone interested in the 0.20 patch- with or without waiting_tasks- can apply
this patch.

Attaching v2 w/ the typo correction

> Currently, job tracker metrics reports waiting tasks as a single field in metrics. It
would be better if we can split waiting tasks into maps and reduces.
