Xiao Kang commented on MAPREDUCE-1674:
--------------------------------------

Thank you for remind.

I have read about the interesting features in hadoop-0.21. We will follow the new features.
Among the six features I listed above, 2 & 3 have been implemeted in hadoop-0.21.

Since great changes have been made to capacity-scheduler, QueueManager and TaskScheduler,
it's difficult to migrate our improvents made against hadoop-0.20.2 to the latest version.
If they are still valuable for the earlier version, sub task will be created for each.
