---------------------------------
Hi [~rkanter], thanks for the review. That is a good suggestion. I uploaded a
new patch YARN-3341.001.patch which will fix 4 findbugs warning.
The last findbugs warning looks like a real bug, I created a separate JIRA
YARN-3355 for findbugs warning at FairScheduler.allocConf.
