------------------------------------
Summary: Scheduler occasionally crashed due to concurrent r/w map
error
Key: YUNIKORN-848
URL: https://issues.apache.org/jira/browse/YUNIKORN-848
Project: Apache YuniKorn
Issue Type: Bug
Components: shim - kubernetes
Reporter: Weiwei Yang
Assignee: Weiwei Yang
Fix For: 1.0.0
It is found that occasionally the scheduler could crash due to concurrent map
r/w error. The root cause is because during the evaluation of the predicates,
we pass a nodesInfo map as a reference to the K8s side, and when concurrently
there is a node being add/remove to the cluster, it could possibly cause the
concurrent read/write issue.
