      Description

      It's is better to catch the ApplicationNotFoundException rather than the parent YarnException and rethrow it when it's not ApplicationNotFoundExcepton

       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;
            }
