Yikun Jiang commented on SPARK-36060:
-------------------------------------

Yep, agree with [~wwei] .

it can be also resolved by [queue 
scheduling|https://issues.apache.org/jira/browse/SPARK-38188] or [resource 
reversation|https://issues.apache.org/jira/browse/SPARK-38187]. If no more 
extra requirement I will also mark this as resolved when queue scheduling and 
resource reversation.

> In a over-subscribed environment we may enter a situation where our requests 
> for more pods are not going to be fulfilled. Adding more requests for more 
> pods is not going to help and may slow down the scheduler. We should detect 
> this situation and hold off on increasing pod requests until the scheduler 
> allocates more pods to us. We have a limited version of this in the Kube 
> scheduler it's self but it would be better to plumb this all the way through 
> to the DA logic.
