Major Description
When YARN_CONTAINER_RUNTIME_DOCKER_RUN_OVERRIDE_DISABLE is true, and a launch command is provided, it is expected that the launch command is provided by the user in exec form.
For example:
"/usr/bin/sleep 6000"
must be changed to:
"/usr/bin/sleep,6000"
If this is not done, the container will never start and will be in a Created state. We should automatically do this conversion vs making the user understand this nuance of using the entrypoint support. Docs should be updated to reflect this change.
