--------------------------------------
Summary: Skip scheduling application if too many pods are
unschedulable
Key: YUNIKORN-3115
URL: https://issues.apache.org/jira/browse/YUNIKORN-3115
Project: Apache YuniKorn
Issue Type: Improvement
Components: core - scheduler
Reporter: Peter Bacsko
Assignee: Peter Bacsko
If an application has too many unschedulable pods, it can drastically affect
scheduling throughput.
In every cycle, we attempt to schedule all pods. If the app has hundreds or
thousands of pods on a large cluster, then it can severly limit the overall
performance of Yunikorn.
We can just skip the application for a given amount of time (90..300 seconds)
if a certain number of pods are pending.
Possible solutions:
1. Percentage of pods vs absolute number (eg 25% vs 100)
2. Partition-wide config vs queue-level setting
