Thanks for clarifying. Yes, it will be a problem, I will handle it.

> I'd like to add a field(retry-times) in ContainerLaunchContext. When AM
> launches containers, it could specify the value. Then NM will re-launch the
> container 'retry-times' times when it fails to run(e.g.exit code is not 0).
> It will save a lot of time. It avoids container localization. RM does not
> need to re-schedule the container. And local files in container's working
> directory will be left for re-use.(If container have downloaded some big
> files, it does not need to re-download them when running again.)
> We find it is useful in systems like Storm.
