Custom SuperUserGroup - Implications for other Hadoop Services?
If we set a custom value for dfs.permissions.superusergroup do we need to add any other Hadoop services to that group in order for the cluster to function normally?
For example, if we set "dfs.permissions.superusergroup=blueManGroup" would we need to add service accounts such as hive, hdfs, oozie, etc. to the "blueManGroup"?
@Wes Floyd are you still having issues? Can you accept the best answer or provide your own solution?
My answer is No. Extract from the above test "I also did not screw up the fact that hdfs is my true superuser as shown by my "old" HDFS home directory process."
