----------------------------------
Summary: inconsistent Node Label resources when NM who has running
application is restarted with changed resource
Key: YARN-7352
URL: https://issues.apache.org/jira/browse/YARN-7352
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.7.1
Reporter: kyungwan nam
steps to reproduce
* Enabled NM Restart (yarn.nodemanager.recovery.enabled = true)
* Changing resources capability for one NM who has running application by
modifying yarn.nodemanager.resource.memory-mb,
yarn.nodemanager.resource.cpu-vcores
* Restarting the NM
nodelabels page in RM web UI show wrong "Total Resources”.
It means resource capability in RMLabelManager does not update according to
changing resource capability.
It could cause wrong scheduling.
