Patrick Wendell updated MAPREDUCE-3600:
---------------------------------------
Attachment: MAPREDUCE-3600.v1.patch
This is a preliminary patch including basic FairScheduling functionality and
tests. Would benefit from review by anyone familiar with existing MR2 RM and
scheduling code.
I had some trouble running dev-support/test-patch.sh (it wanted to build and
examine every sub-project which was taking > 1 hour). Any advise on how to use
that tool with a narrower scope is appreciated.

> This covers the addition of the Fair Scheduler to the MR2 infrastructure.
> This patch will represent the minimum functional FairScheduler in MR2. It
> will be limited to a configuration file reader, functionality to calculate
> fair shares, and hooks into the actual MR2 scheduling code.
> It will not include delay scheduling, preemption, or a web UI, which will be
> handled in separate JIRA's.
