-----------------------------------
Summary: Race condition in ResourceTrackerService: potential wrong
diagnostics messages
Key: YARN-3826
URL: https://issues.apache.org/jira/browse/YARN-3826
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.7.0
Reporter: Chengbing Liu
Since we are calling {{setDiagnosticsMessage}} in {{nodeHeartbeat}}, which can
be called concurrently, the static {{resync}} and {{shutdown}} may have wrong
diagnostics messages in some cases.
On the other side, these static members can hardly save any memory, since the
normal heartbeat responses are created for each heartbeat.
