Rohith updated YARN-3733:
-------------------------
Attachment: 0001-YARN-3733.patch
The updated patch that fixes for 2nd and 3rd scenarios(This issue scenario
fixes) in above table and refactored the test code.
As a overall solution that solves input combination like 4th and 5th from above
table, need to explore more on how to define fraction and how to decide which
one is dominant. Any suggestions on this?
> DominantRC#compare() does not work as expected if cluster resource is empty
