@Ram D Ram, You are right on the support. I suggest to wait until the official support before running into production. http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.2/bk_yarn_resource_mgt/content/enabling_cgroups.html Hint: On RHEL7, the cpu and cpuacct controllers are managed together by default. The default directory is /sys/fs/cgroup/cpu,cpuacct . Due to the parsing logic of the container-executor, the presence of the comma in this path may lead to failures when initializing the NodeManager (when using the LinuxContainerExecutor ). To avoid this issue, create your own directory (such as /sys/fs/cgroup/hadoop/cpu ) and set the yarn.nodemanager.linux-container-executor.cgroups.mount property to true . This will allow the NodeManager to mount the cpu controller, and YARN will be able to enforce CPU limits. If you would like to mount CGroups yourself, you should set the yarn.nodemanager.linux-container-executor.cgroups.mount property to false and ensure that the hierarchy specified in the yarn.nodemanager.linux-container-executor.cgroups.hierarchy property exists in the mount location. You must also ensure that there are no commas anywhere in the path names.
