             Summary: 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: Siddharth Seth


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).
