-----------------------------
Summary: Clean up bad exception catching practices in
TestYarnClient
Key: YARN-5560
URL: https://issues.apache.org/jira/browse/YARN-5560
Project: Hadoop YARN
Issue Type: Test
Reporter: Sean Po
Assignee: Sean Po
In TestYarnClient, tests commonly wrap methods that throw exceptions in a try
catch statement similar to the following:
{{try {}}
{{client.submitApplication(context);}}
{{} catch (Exception e) {}}
{{Assert.fail("Exception is not expected.");}}
{{}}}
This hides useful error messages, and surfaces less helpful ones.
