Vinod Kumar Vavilapalli commented on YARN-2168:
-----------------------------------------------

Thanks Chris, that makes sense, I supposed you will create client/admin specific JIRAs under
YARN-1492?

IAC, it will also be great to review from the view of APIs - the patch on this JIRA is reviewable
from that POV (even if we don't commit it this way)?

> Define and implement the following protocols and protocol messages using protobufs:
> * ClientSCMProtocol - The protocol between the yarn client and the cache manager. This
protocol controls how resources in the cache are claimed and released.
> ** UseSharedCacheResourceRequest
> ** UseSharedCacheResourceResponse
> ** ReleaseSharedCacheResourceRequest
> ** ReleaseSharedCacheResourceResponse
> * SCMAdminProtocol - This is an administrative protocol for the cache manager. It allows
administrators to manually trigger cleaner runs.
> ** RunSharedCacheCleanerTaskRequest
> ** RunSharedCacheCleanerTaskResponse
> * NMCacheUploaderSCMProtocol - The protocol between the NodeManager and the cache manager.
This allows the NodeManager to coordinate with the cache manager when uploading new resources
to the shared cache.
> ** NotifySCMRequest
> ** NotifySCMResponse
