> In order to set the group for the task-controller binary in Hadoop 1 or container-executor
binary in Hadoop 2:
> h5. For Hadoop 1.x stack secure cluster:
> * Stop MapReduce service.
> * Reconfigure mapreduce.tasktracker.group property in MapReduce > Configs > Advanced
section.
> * Manually create the group per the value entered in mapreduce.tasktracker.group on each
tasktracker host. 
> * Add mapred user to that group. 
> * Start the MapReduce service.
> * This reconfigures the mapreduce.tasktracker.group property in /etc/hadoop/taskcontroller.cfg
 and also sets the group ownership for the /usr/lib/hadoop/bin/task-controller binary.
> * Run MapReduce smoke test. Smoke test should pass.
> h5. For Hadoop 2.x stack secure cluster:
> * Stop Yarn service.
> *  Reconfigure yarn.nodemanager.linux-container-executor.group property in YARN >
Configs > Advanced section. 
> * Manually create the group per the value entered in yarn.nodemanager.linux-container-executor.group
on each nodemanager host.
> * Add yarn user to that group. 
> * Start the YARN service.
> * This reconfigures the yarn.nodemanager.linux-container-executor.group property in /etc/hadoop/container-executor.cfg
and also set the group value for the /usr/lib/hadoop-yarn/bin/container-executor binary.
> *  Run YARN smoke test. Smoke test should pass.
