Xuan Gong commented on YARN-1521:
---------------------------------
But first of all, we need to find which apis can be marked as Idempotent
Here is the list of APIs that I think we can mark as Idempotent:
* ResourceTracker
** registerNodeManager
** nodeHeartbeat
* ResourceManagerAdministrationProtocol
** refreshQueues
** refreshNodes
** refreshSuperUserGroupsConfiguration
** refreshUserToGroupsMappings
** refreshAdminAcls
** refreshServiceAcls
* ApplicationClientProtocol
** forceKillApplication
** getApplicationReport (already marked)
** getClusterMetrics
** getApplications
** getClusterNodes
** getQueueInfo
** getQueueUserAcls
** getApplicationAttemptReport
** getApplicationAttempts
** getContainerReport
** getContainers
> Mark appropriate protocol methods with the idempotent annotation or
> AtMostOnce annotation
