Junping Du commented on YARN-1503:
----------------------------------
bq. Anyway, these are advanced stuff and not conflicting with core change.
I'll open separate jira and talk about how to implement it when it comes.
Sure. The plan sound good to me.
Just a notification for guys on watching this jira, I am starting to review the
first patch (YARN-5557) under this umbrella which should be irrelevant of our
discussions above. Please let me know if you have any concerns.
> Support making additional 'LocalResources' available to running containers
> --------------------------------------------------------------------------

> Key: YARN-1503
> URL: https://issues.apache.org/jira/browse/YARN-1503
> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: Siddharth Seth
> Assignee: Jian He
> Attachments: Continuous-resource-localization.pdf

>
> 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).
