------------------------------------
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).
