             Summary: Document the behavior of queue quota incase of hierarchical queues
                 Key: YUNIKORN-308
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-308
             Project: Apache YuniKorn
          Issue Type: Task
          Components: documentation
            Reporter: Ayub Pathan


When a hierarchical queues are configured with quota, there are some assumptions which needs to be documented. 
 # A child’s max **must** be smaller than parent max (need to implement if not done)
 # sum of max resources of all children for a parent does **not** have to be smaller than the parent max
 # Sum of used resources of all children under a parent should always be smaller than the parent max.

 

One such example where the #3 can be demonstrated is below.
||Queue||MaxResource
 Configured||Time T1
 (Resource
 Request)||Time T2
 (Resource
 Request)||Time T3
 (Resource
 Request)||
|Parent|1000|200|600|1100 (x)(x)|
|Child1|200|200|200|200|
|Child2|500|-|400|400|
|Child3|500|-|-|500 ((x) (x)as it exceeds total usage)|
