-----------------------------------

Hi [~Naganarasimha]

Thanks for finding this, my bad, I overlooked the message

bq. +1 findbugs  hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common generated 0 new + 1 unchanged
- 1 fixed = 1 total (was 2)

I guess I was just looking at +1 but did not saw 1 unchanged. Sorry about that. I just tried
you suggestion and that fix the problem, thank you very much. Should I reopen this one or
file a new JIRA to get this fixed? I have attached the patch in this JIRA.

Thank you.
