[jira] [Comment Edited] (YARN-8043) Add the exception message for
failed launches running under LCE
[ https://issues.apache.org/jira/browse/YARN-8043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16403744#comment-16403744 ]

------------------------------------------------------------
I believe the intent of the {{output}} and {{errorOutput}} fields in {{ContainerExecutionException}} was to represent stdout/stderr for a shell command.The easy fix here is to add a {{getMessage}} call to the diagnostics output and clearly display what "errorOutput" is. I'll put up a patch that does that.

> If a {{ContainerExecutionException}} is thrown during container launch under LCE information is added to the diagnostics for the container regarding the failure. The diagnostic's output includes the container id, exit code, "error output" and "shell output", with the expectation that the relevant exception details are in the "error output".
> {{ContainerExecutionException}} has several constructors, with the most commonly used being the one that accepts a String. This form does not put the exception details into the "error output". This makes it difficult for the user to troubleshoot the failure.
