> Key: YUNIKORN-1632
> URL: https://issues.apache.org/jira/browse/YUNIKORN-1632
> Project: Apache YuniKorn
> Issue Type: Bug
> Reporter: Eli Schiff
> Assignee: Eli Schiff
> Priority: Major
> Fix For: 1.3.0

>
> In my cluster I am seeing occasional events like this on some of my pods
> which causes them to get stuck.
> {code:java}
> 54m Warning OutOfpods
> pod/tg-spark-executor-640b4349263cc74570ae3a1e-0 Node didn't have enough
> resource: pods, requested: 1, used: 12, capacity: 12{code}
>
> It mostly happens when a bunch of small pods get created all at once and all
> get assigned to the same node. That node could fit the pods based on
> cpu/memory alone. The limiting factor here is the pod limit.
> Here is an example of a node when I get a state-dump (note that this node is
> not the one that was out of capacity, I could not get the statedump in time.
> This is just a random example node.)
> Note how the capacity section shows vcore, memory, and pods among others. The
> available section subtracts the vcore and memory correctly but pods is still
> at 12 which is the same as the capacity even though there are pods on this
> node.
