Latest patch LGTM. > Improve exception information on AM launch crashes > -------------------------------------------------- > > Key: YARN-2242 > URL: https://issues.apache.org/jira/browse/YARN-2242 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Li Lu > Assignee: Li Lu > Fix For: 2.6.0 > > Attachments: YARN-2242-070115-2.patch, YARN-2242-070814-1.patch, > YARN-2242-070814.patch, YARN-2242-071114.patch, YARN-2242-071214.patch, > YARN-2242-071414.patch > > > Now on each time AM Container crashes during launch, both the console and the > webpage UI only report a ShellExitCodeExecption. This is not only unhelpful, > but sometimes confusing. With the help of log aggregator, container logs are > actually aggregated, and can be very helpful for debugging. One possible way > to improve the whole process is to send a "pointer" to the aggregated logs to > the programmer when reporting exception information. -- This message was sent by Atlassian JIRA (v6.2#6252)
