[jira] [Resolved] (YARN-7381) Enable the configuration:
yarn.nodemanager.log-container-debug-info.enabled by default in
yarn-default.xml
[ https://issues.apache.org/jira/browse/YARN-7381?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eric Yang resolved YARN-7381.
-----------------------------
Resolution: Fixed
When NM_LOG_CONTAINER_DEBUG_INFO is enabled, and there is a problem to execute container script. A ExitCodeException would be thrown to notify the execution failure. By default, I think this is correct to make sure failure are notified to caller. The past behavior swallows the exception, which is not exactly correct. Most people don't use DefaultContainerExecutor, and container launcher code is usually successful. This is the reason that swallowed exception was not noticeable.
TestContainerLaunch unit test is not quite accurate because the script instructed to execute "hello" script, which does not exist. Hence, the throwing of exception is the proper behavior. I am inclined to close this issue as fixed. When ExitCodeException triggers more exception else where, it will help developer to look at the root causes that trigger launcher failures more closely.
