Description

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 "/sys/fs/cgroup/cpu,cpuacct/hadoop-yarn/contain_id/tasks".
We should someother character instand of ",".
