    Attachment: YARN-2056.201411142002.txt

[~leftnoteasy], Thank you for all of your help. Uploading new patch.

bq. Instead of multiply you should use multiplyAndNormalizeUp here.
Using {{multiplyAndNormalizeUp}} helps. However, for the use case in {{testHierarchicalLarge}},
the rounding is still different with the new algorithm (7 and 5 instead of 9 and 4).

bq. Actually I think we should consider minimum_allocation in preemption policy, we can address
that in a separated JIRA. 
Would you please create a new JIRA and elaborate on this further?
bq. {{testDisablePreemptionOverCapPlusPending}}
Since the result is not changed before/after we set preemption queue, I think it is unnecessary,
I would suggest to take it out.
I removed this test.
