Wangda Tan commented on YARN-4422: ---------------------------------- Committed to branch-2.8. > Generic AHS sometimes doesn't show started, node, or logs on App page > --------------------------------------------------------------------- > > Key: YARN-4422 > URL: https://issues.apache.org/jira/browse/YARN-4422 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Eric Payne > Assignee: Eric Payne > Fix For: 3.0.0, 2.8.0, 2.7.3 > > Attachments: AppAttemptPage no container or node.jpg, AppPage no logs > or node.jpg, YARN-4422.001.patch > > > Sometimes the AM container for an app isn't able to start the JVM. This can > happen if bogus JVM options are given to the AM container ( > {{-Dyarn.app.mapreduce.am.command-opts=-InvalidJvmOption}}) or when > misconfiguring the AM container's environment variables > ({{-Dyarn.app.mapreduce.am.env="JAVA_HOME=/foo/bar/baz}}) > When the AM container for an app isn't able to start the JVM, the Application > page for that application shows {{N/A}} for the {{Started}}, {{Node}}, and > {{Logs}} columns. It _does_ have links for each app attempt, and if you click > on one of them, you go to the Application Attempt page, where you can see all > containers with links to their logs and nodes, including the AM container. > But none of that shows up for the app attempts on the Application page. > Also, on the Application Attempt page, in the {{Application Attempt > Overview}} section, the {{AM Container}} value is {{null}} and the {{Node}} > value is {{N/A}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
