>
> In TestYarnClient, tests commonly wrap methods that throw exceptions in a try
> catch statement similar to the following:
> {code}
> try {
> client.submitApplication(context);
> } catch (Exception e) {
> Assert.fail("Exception is not expected.");
> }
> {code}
> This hides useful error messages, and surfaces less helpful ones.
