Description

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
