Shane Kumpf commented on YARN-7914:
-----------------------------------
Attaching a patch to fix the issue. The exit code handling logic incorrectly
depended on obtaining a valid PID for the container. Even when a PID isn't
available, we still need to get the exit code for the container to properly
fail cases where the launch_command is invalid or simply calls exit with a
non-zero value.

> container, the exitcode will not be properly obtained via {{docker inspect.}}
> This results in containers successfully completing when they should fail.
