Andrey Stepachev commented on YARN-1864:
----------------------------------------

I've updated patch with three additional rules 'userMatch', 
'primaryGroupMatch', and 'secondaryGroupMatch'.
Now testcase like this works:
{code}
  @Test
  public void testSpecifiedUserPolicyWithPrefix() throws Exception {
    StringBuffer sb = new StringBuffer();
    sb.append("<queuePlacementPolicy>");
    sb.append("  <rule name='specified' parent='granted'/>");
    sb.append("  <rule name='userMatch'  parent='admin' 
pattern='admin1|admin4'/>");
    sb.append("  <rule name='primaryGroupMatch' parent='admin.primg' 
pattern='admin2group.*'/>");
    sb.append("  <rule name='secondaryGroupMatch' parent='admin.secg' 
pattern='admin3subgroup1'/>");
    sb.append("  <rule name='user'  parent='guests'/>");
    sb.append("</queuePlacementPolicy>");
    QueuePlacementPolicy policy = parse(sb.toString());
    
assertEquals("root.granted.specifiedq",policy.assignAppToQueue("specifiedq", 
"someuser"));
    assertEquals("root.admin.admin1", policy.assignAppToQueue("default", 
"admin1"));
    assertEquals("root.admin.primg.admin2", policy.assignAppToQueue("default", 
"admin2"));
    assertEquals("root.admin.secg.admin3", policy.assignAppToQueue("default", 
"admin3"));
    assertEquals("root.guests.someuser", policy.assignAppToQueue("default", 
"someuser"));
    assertEquals("root.guests.otheruser", policy.assignAppToQueue("default", 
"otheruser"));

{code}

> In Fair Scheduler, we want to be able to create user queues under any parent 
> queue in the hierarchy. For eg. Say user1 submits a job to a parent queue 
> called root.allUserQueues, we want be able to create a new queue called 
> root.allUserQueues.user1 and run user1's job in it.Any further jobs submitted 
> by this user to root.allUserQueues will be run in this newly created 
> root.allUserQueues.user1.
> This is very similar to the 'user-as-default' feature in Fair Scheduler which 
> creates user queues under root queue. But we want the ability to create user 
> queues under ANY parent queue.
> Why do we want this ?
> 1. Preemption : these dynamically created user queues can preempt each other 
> if its fair share is not met. So there is fairness among users.
> User queues can also preempt other non-user leaf queue as well if below fair 
> share.
> 2. Allocation to user queues : we want all the user queries(adhoc) to consume 
> only a fraction of resources in the shared cluster. By creating this 
> feature,we could do that by giving a fair share to the parent user queue 
> which is then redistributed to all the dynamically created user queues.
