Eric Yang commented on YARN-8805:
---------------------------------
Patch 001 allows using space as delimiter. This patch can make launch command
more user friendly by replacing space with comma in the backend. However, this
patch does not try to solve limitation of serialization method used in .cmd
file format.
> Automatically convert the launch command to the exec form when using
> entrypoint support

>
> 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.
