Jian He commented on YARN-814: ------------------------------ bq. When an exception happens in LinuxContainerExecutor.startLocalizer(), the exception's message eventually is set as diagnostics at ResourceLocalizationService.LocalizerRunner.run()(+996-+997). But the shell output is lost. Can you consistently fix this? The patch should already handle this. bq. deleteAsUser errors are missing too, but I remember there's a separate ticket will do this in a separate ticket Other comments fixed > Difficult to diagnose a failed container launch when error due to invalid > environment variable > ---------------------------------------------------------------------------------------------- > > Key: YARN-814 > URL: https://issues.apache.org/jira/browse/YARN-814 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Hitesh Shah > Assignee: Jian He > Attachments: YARN-814.1.patch, YARN-814.2.patch, YARN-814.3.patch, > YARN-814.4.patch, YARN-814.5.patch, YARN-814.6.patch, YARN-814.patch > > > The container's launch script sets up environment variables, symlinks etc. > If there is any failure when setting up the basic context ( before the actual > user's process is launched ), nothing is captured by the NM. This makes it > impossible to diagnose the reason for the failure. > To reproduce, set an env var where the value contains characters that throw > syntax errors in bash. -- This message is automatically generated by JIRA.
