> Prior to YARN-5366, {{container-executor}} would remove the Docker container 
> when it exited. The removal is now handled by the 
> {{DockerLinuxContainerRuntime}}. {{ContainerRelaunch}} is intended to reuse 
> the workdir from the previous attempt, and does not call {{cleanupContainer}} 
> prior to {{launchContainer}}. The container ID is reused as well. As a 
> result, the previous Docker container still exists, resulting in an error 
> from Docker indicating the a container by that name already exists.
