> Issue Type: Improvement

> We have a use case, where additional resources (jars, libraries etc) need to
> be made available to an already running container. Ideally, we'd like this to
> be done via YARN (instead of having potentially multiple containers per node
> download resources on their own).
> Proposal:
> NM to support an additional API where a list of resources can be specified.
> Something like "localiceResource(ContainerId, Map<String, LocalResource>)
> NM would also require an additional API to get state for these resources -
> "getLocalizationState(ContainerId)" - which returns the current state of all
> local resources for the specified container(s).
