---------------------------------------------
Summary: Cannot set guaranteed resources for a child when they are
not defined for the parent queue.
Key: YUNIKORN-1898
URL: https://issues.apache.org/jira/browse/YUNIKORN-1898
Project: Apache YuniKorn
Issue Type: Bug
Reporter: Sahaaj Singh Chawla
Assignee: Sahaaj Singh Chawla
When a particular resource(s) is not defined in the guaranteed resource for a
parent queue, Yunikorn doesn't allow us to define that particular resource in
the guaranteed quota for children of that particular parent.
For example,
If we have a hierarchy like this:
{noformat}
root
- parent1
- child1{noformat}
The quota for the parent1 is as follows:
{noformat}
Max:
memory = 1000
vcores = 1000
Guaranteed:
memory = 800
{noformat}
The quota which we want for child1:
{noformat}
Max:
memory = 500
vcores. = 500
Guaranteed:
memory = 200
vcores = 200
{noformat}
When we try to create the child1 under parent1 with this quota, we get an error
from Yunikorn which states that guaranteed resource of the parent is smaller
than the sum of guaranteed resources of the children.
The error message that we get back is as follows:
guaranteed resource of parent map[memory:800] is smaller than sum of guaranteed
resources map[memory:200 vcore:200] of the children for queue parent1
{color:#172b4d}In such a case where we have no guaranteed quota defined for a
particular resource, it should be checked against the max quota of the queue
and allow the creation of the queue if the guaranteed quota of the child fits
in the max quota of the parent.{color}
