Shane Kumpf commented on YARN-8043:
-----------------------------------
I believe the intent for the {{output}} and {{errorOutput}} fields in
{{ContainerExecutionException}} were meant 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.

> Key: YARN-8043
> URL: https://issues.apache.org/jira/browse/YARN-8043
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Shane Kumpf
> Priority: Major
>
> 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.
