Summary: Catch ApplicationNotFoundException instead of parent
YarnException in YarnClient and AppReportFetcher
Key: YARN-3976
URL: https://issues.apache.org/jira/browse/YARN-3976
Project: Hadoop YARN
Issue Type: Bug
Affects Versions: 2.7.1
Reporter: Mit Desai
Assignee: Mit Desai
It's is better to catch the ApplicationNotFoundException rather than the parent
YarnException and rethrow it when it's not ApplicationNotFoundExcepton
{noformat}
catch (YarnException e) {
if (!historyServiceEnabled) {
// Just throw it as usual if historyService is not enabled.
throw e;
}
// Even if history-service is enabled, treat all exceptions still the same
// except the following
if (!(e.getClass() == ApplicationNotFoundException.class)) {
throw e;
}
{noformat}
