problems of FairScheduler in hadoop2.2.0
Hi, all

When I run jobs in hadoop 2.2.0,  I encounter a problem. Suddenly, the hadoop resourcemanager cannot work normally: When I submit jobs and the jobs’ status all are “submitted” and cannot run.
I cannot find any answers in the internet, who can give me some help? Thanks.

The resourcemanager log is as follows:
