---------------------------------
Summary: YuniKorn stopped scheduling new containers with negative
vcore in queue
Key: YUNIKORN-2731
URL: https://issues.apache.org/jira/browse/YUNIKORN-2731
Project: Apache YuniKorn
Issue Type: Bug
Components: core - scheduler
Affects Versions: 1.5.1
Reporter: Xi Chen
We have encountered this issue in one of our clusters every a few days. We are
running a version that is built from branch
[https://github.com/apache/yunikorn-k8shim/commits/branch-1.5/] commit
fb4e3f11345e6a9866dfaea97770c94b9421807b.
Here is our configuration of queues.yaml.
{code:java}
partitions:
- name: default

type: binpacking

properties:

The issue is that at some point the scheduler would stop starting new
containers, and there would be 0 containers running finally and lots of
applications in Accepted status.
There are some logs that contains negative vcore resource, and these logs are
highly corralated with this issue in timeline.

There are also some warnings about Scheduler is not healthy, but those logs
