fair scheduler deadlock at FairSchedulerUpdateThread

I current use hadoop2.6.0 configured with fair scheduler.
After trying Hive on Tez, it seems that fair scheduler get deadlock.

The output of jstack, jmap and resourcemanager log is here:
https://drive.google.com/file/d/0B7zV3Ct1fa9dQWJvZW9hR0Q0dHc/view

And deadlock occurred at 2015-07-27 16:10, so you guys can focus at this
time when read resourcemanager log.

>From jstack, it seemed  hung at FairSchedulerUpdateThread

Hope above information can help debug this issue.
