             Summary: CgroupsLCEResourcesHandler does not support the default 
Redhat 7/CentOS 7
                 Key: YARN-2686
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
            Reporter: Beckham007

CgroupsLCEResourcesHandler uses "," to seprating resourcesOption.
Redhat 7 use "/sys/fs/cgroup/cpu,cpuacct" as the cpu mount dir. So 
container-executor would use the wrong path "/sys/fs/cgroup/cpu" as the 
container task file. It should be 
We should someother character instand of ",".
