Description

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.

while(true) {
        appReport = yarnClient.getApplicationReport(appId);
        Thread.sleep(1000);
        LOG.info("AppStatus:" + appReport.getFinalApplicationStatus());
        LOG.info("Diagnostics:" + appReport.getDiagnostics());
        ....
}

Output:

AppStatus:FAILED
Diagnostics: // empty

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