[jira] [Created] (YARN-8427) Don't start opportunistic containers
at container scheduler/finish event with over-allocation
Haibo Chen created YARN-8427:
--------------------------------
Summary: Don't start opportunistic containers at container scheduler/finish event with over-allocation
Key: YARN-8427
URL: https://issues.apache.org/jira/browse/YARN-8427
Project: Hadoop YARN
Issue Type: Improvement
Components: nodemanager
Reporter: Haibo Chen
Assignee: Haibo Chen
As discussed in YARN-8250, we can stop opportunistic containers from being launched at container scheduler/finish events if the node is already over-allocating itself. This can mitigate the issue that too many opportunistic containers can be launched and then quickly killed.
