Siddharth Seth commented on YARN-4554:
--------------------------------------
Please go ahead. Separating the diagnostics per appAttempt in the main report
would be useful. Something like "[appAttempt1=...], [appAttempt2=...]"
> ApplicationReport.getDiagnostics does not return diagnostics from individual
> attempts

> Key: YARN-4554
> URL: https://issues.apache.org/jira/browse/YARN-4554
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.6.0
> Reporter: Siddharth Seth
> Assignee: Sunil G
>
> For an Application with ApplicationReport.getFinalApplicationStatus=FAILED
> and ApplicationReport.getYarnApplicationState=FINISHED -
> ApplicationReport.getDiagnostics returns an empty string.
> Instead I had to use ApplicationReport.getCurrentApplicationAttemptId,
> followed by getApplicationAttemptReport to get diagnostics for the attempt -
> which contained the information I had used to unregister the app.
