Summary: Should use equals when compare Resource in
RMNodeImpl#ReconnectNodeTransition
Key: YARN-3780
URL: https://issues.apache.org/jira/browse/YARN-3780
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.7.0
Reporter: zhihai xu
Assignee: zhihai xu
Priority: Minor
Should use equals when compare Resource in RMNodeImpl#ReconnectNodeTransition
to avoid unnecessary NodeResourceUpdateSchedulerEvent.
The current code use {{!=}} to compare Resource totalCapability, which will
compare reference not the real value in Resource. So we should use equals to
compare Resource.
