Sean Po updated YARN-4957:
--------------------------
Attachment: YARN-4957.v7.patch
YARN-4957.v7.patch addresses Carlo's comments and fixes the checkstyle and
javadoc issues. Two check-style issues with regards to method length will
remain - these are pre-existing, and a refactor will be out of the scope of
this JIRA.
