Unable to initialize hive / run a job due to "non-leaf queue" error

[#1]

SYMPTOM: On invoking a mapreduce job or invoking a hive shell (incase where we use tez execution engine, which is default) which involves spinning up a mapreduce container on the mapreduce queue), we get the below error :

[hive@sumeshhdpn2 root]$ hadoop jar /usr/hdp/2.2.4.2-2/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi 1 10
Number of Maps  = 1
Samples per Map = 10

ROOT CAUSE: This is triggered when requestor / user create a queue under the "default" queue. The queue "default" should not have any child queue created under. An example of this would be as below: Here we have a queue called "default.test" queue created under "default" queue. Due to this when we submit any mapreduce job or hive shell, we get the exceptions as shown above. RESOLUTION / WORKAROUND: To address this issue, remove the queue under the default queue. If a queue needs to be created, we can create a queue under "root" and assign the required resources for it.
