Some might be but many(findbugs and testcase) are not related to this jira, 
hence planning to raise seperate jira to handle the same.
And some findbugs (like Unchecked/unconfirmed cast from 
org.apache.hadoop.yarn.server.resourcemanager.metrics.SystemMetricsEvent ) not 
planning to handle as its same as earlier code & if checks doesnt make sense 
here

Understood. We should try to resolve the ones that make sense but don't have to 
be pedantic. By the way, note that I filed a separate JIRA for the unit test 
issues that already exist on YARN-2928 (YARN-3562).

Well AFAIK it only affects readability here and had taken entry set iterator 
here as its generally preferred in terms of performance and concurrency (not 
relevance here). If you feel readability is a issue then can modify to simple 
loop

That's fine. It was a style nit (if that wasn't clear).
