> 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:
> {code:java}
> "/usr/bin/sleep 6000"{code}
> must be changed to:
> {code}"/usr/bin/sleep,6000"{code}
> 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.
