Vinod Kumar Vavilapalli commented on YARN-2168:
-----------------------------------------------
Few comments on the APIs
- Let's mark all the APIs as evolving, or may be even unstable.
- The setters for responses and objects that are supposed to be only created
by the server should be marked Private - we don't expect users to use them. For
e.g. UseSharedCacheResourceResponse.setPath()
- Let's move SCMAdminProtocol and all related records to
org.apache.hadoop.yarn.server.api &
org.apache.hadoop.yarn.server.api.protocolrecords packages.
- We are using checksum, key, resource-key to all refer to the same entity.
Shall we standardize on resource-key?

> This jira is meant to be used to review the main shared cache APIs. They are
> as follows:
> * 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
