Karthik Kambatla updated YARN-2194:
-----------------------------------
          Component/s: nodemanager
          Description: 
In RHEL7, the CPU controller is named "cpu,cpuacct". The comma in the 
controller name leads to container launch failure. 

RHEL7 deprecates libcgroup and recommends the user of systemd. However, systemd 
has certain shortcomings as identified in this JIRA (see comments). 

This JIRA only fixes the failure, and doesn't try to use systemd.

  was:   In previous versions of RedHat, we can build custom cgroup hierarchies 
with use of the cgconfig command from the libcgroup package. From RedHat 7, 
package libcgroup is deprecated and it is not recommended to use it since it 
can easily create conflicts with the default cgroup hierarchy. The systemd is 
provided and recommended for cgroup management. We need to add support for this.

             Priority: Critical  (was: Major)
     Target Version/s: 2.8.0
    Affects Version/s: 2.7.0
           Issue Type: Bug  (was: Improvement)
