> Key: FLINK-4089
> URL: https://issues.apache.org/jira/browse/FLINK-4089
> Project: Flink
> Issue Type: Bug
> Reporter: Ted Yu
> Assignee: Maximilian Michels
> Fix For: 1.1.0, 1.0.4
>
>
> Here is related code:
> {code}
> if(pollingRunner == null) {
> LOG.warn("YarnClusterClient.getApplicationStatus() has been called on
> an uninitialized cluster." +
> "The system might be in an erroneous state");
> }
> ApplicationReport lastReport = pollingRunner.getLastReport();
> {code}
> If pollingRunner is null, NPE would result from the getLastReport() call.
