Robert Parker commented on YARN-165: ------------------------------------ I am getting an NPE on the test added by YARN-165-branch23.patch > RM should point tracking URL to RM web page for app when AM fails > ----------------------------------------------------------------- > > Key: YARN-165 > URL: https://issues.apache.org/jira/browse/YARN-165 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager > Affects Versions: 2.0.3-alpha, 0.23.5 > Reporter: Jason Lowe > Assignee: Jason Lowe > Priority: Blocker > Attachments: YARN-165-branch23.patch, YARN-165.patch > > > Currently when an ApplicationMaster fails the ResourceManager is updating the > tracking URL to an empty string, see > RMAppAttemptImpl.ContainerFinishedTransition. Unfortunately when the client > attempts to follow the proxy URL it results in a web page showing an HTTP 500 > error and an ugly backtrace because "http://" isn't a very helpful tracking > URL. > It would be much more helpful if the proxy URL redirected to the RM webapp > page for the specific application. That page shows the various AM attempts > and pointers to their logs which will be useful for debugging the problems > that caused the AM attempts to fail. -- This message is automatically generated by JIRA.
