Wangda Tan commented on YARN-6610:
----------------------------------
[~templedf],
Thanks for updating patch, I did some test and got some amazing results:
By executing test: {{mvn test
-Dtest=TestCapacityScheduler#testUserLimitThroughput
-DRunUserLimitThroughput=true}}
For throughput (higher is better)
1) YARN-3926 w/o the patch: 50505.05
2) trunk: 57142.855
3) 3926 + 6610 (perf): {color:red}606060.6 (!!){color}
4) 3926 + 6610 (006): 46403.71
Since YARN-3926 is rebased to trunk, I did some rebases while doing the test as
well. The number looks great, I just hope we didn't accidentally introduce some
issues. I will do some other verifications as well.

> The {{dominant}} param assumes there are only two resources, i.e. true means
> to compare the dominant, and false means to compare the subordinate. Now
> that there are _n_ resources, this parameter no longer makes sense.
