Use case
There are 2 groups Analytics and DW. We want to split the cluster resources between these 2 groups.
User - neeraj belongs to Analytics group.
User - dwuser belongs to DW group
User neeraj is not allowed to use Default and dwuser queue. Be default, all the jobs submitted by user neeraj must go to it's assigned queue.
User dwuser is not allowed to use Default and Analytics queue. By default, all the jobs submitted by user dwuser must go to it's assigned queue.
Environment
HDP 2.3 (Hortonworks Data Platform) and Ambari 2.1
This tutorial completely independent of Hadoop distribution. Yarn is must i,e Hadoop 2.x
I will be using Capacity Scheduler view to configure queues.
