Eric Badger commented on YARN-7189:
-----------------------------------
The TestDockerContainerRuntime failures are unrelated to this patch and should
be fixed by the backporting of YARN-7810 to branch-3.0.
I'm not sure how to write a test for this. I've manually tested this by running
a cluster with invalid {{mapreduce.map.java.opts}} and seeing that all
containers are cleaned up with the patch (and not cleaned up without it). If
anyone has suggestions, I'd be happy to implement.

> Once the docker run command is executed, the docker container is created
> unless the return code is 125 meaning that the run command itself failed
> (https://docs.docker.com/engine/reference/run/#exit-status). Any error that
> happens after the docker run needs to remove the container during cleanup.
> {noformat:title=container-executor.c:launch_docker_container_as_user}
> snprintf(docker_command_with_binary, command_size, "%s %s", docker_binary,
> docker_command);
> fprintf(LOGFILE, "Launching docker container...\n");
> FILE* start_docker = popen(docker_command_with_binary, "r");
> {noformat}
> This is fixed by YARN-5366, which changes how we remove containers. However,
> that was committed into 3.1.0. 2.8, 2.9, and 3.0 are all affected
