---------------------------------
Summary: Support ContainerRelaunch for Docker containers
Key: YARN-7973
URL: https://issues.apache.org/jira/browse/YARN-7973
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Shane Kumpf
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.
