--------------------------------

             Summary: Diagnostics is delayed to passed to ApplicationReport
                 Key: YARN-2560
                 URL: https://issues.apache.org/jira/browse/YARN-2560
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Jeff Zhang


The diagnostics of Application may be delayed to pass to ApplicationReport. Here's one example when ApplicationStatus has changed to FAILED, but the diagnostics is still empty. And the next call of getApplicationReport could get the diagnostics.
{code}
while(true) {
        appReport = yarnClient.getApplicationReport(appId);
        Thread.sleep(1000);
        LOG.info("AppStatus:" + appReport.getFinalApplicationStatus());
        LOG.info("Diagnostics:" + appReport.getDiagnostics());
        ....
}
{code}

*Output:*
{code}
AppStatus:FAILED
Diagnostics: // empty

// get diagnostics for the next getApplicationReport
AppStatus:FAILED
Diagnostics: // diagnostics info here
{code}
