> 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}
