Subject [jira] [Commented] (YARN-3044) [Event producers] Implement RM writing app lifecycle events to ATS
Date Wed, 29 Apr 2015 21:43:06 GMT

    [ https://issues.apache.org/jira/browse/YARN-3044?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14520322#comment-14520322

Sangjin Lee commented on YARN-3044:

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).
