Naganarasimha G R commented on YARN-4624:
-----------------------------------------
[~sunilg],
bq. we can group this new metrics (maxAMPercentageLimit etc) in other DAO
object and can use it.
If this is the alternate approach would it bring incompatibility later ? If so
better to address in this jira and get it fixed as part of 2.8.
Well if the approach was already discussed then we can go ahead with V3 patch
and just add it to findbugs exclude file.
