Bikas Saha commented on YARN-873: --------------------------------- Having a return statement in a catch/finally block is not recommended normally. We could print the message and re-throw the exception or simply not catch the exception. Also, this way the cmd line would exit with non-zero exit code. {code} + } catch (ApplicationNotFoundException ex) { + sysout.println("Application with id '" + + applicationId + "' doesn't exist in RM."); + return; + } {code} > YARNClient.getApplicationReport(unknownAppId) returns a null report > ------------------------------------------------------------------- > > Key: YARN-873 > URL: https://issues.apache.org/jira/browse/YARN-873 > Project: Hadoop YARN > Issue Type: Sub-task > Affects Versions: 2.1.0-beta > Reporter: Bikas Saha > Assignee: Xuan Gong > Attachments: YARN-873.1.patch, YARN-873.2.patch, YARN-873.3.patch > > > How can the client find out that app does not exist? -- This message is automatically generated by JIRA.
