> 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
> Assignee: Chengbing Liu
> Attachments: YARN-3826.01.patch
>
>
> 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.
