Subject [jira] [Commented] (YARN-3671) Integrate Federation services with ResourceManager
Date Thu, 25 Aug 2016 08:58:21 GMT

    [ https://issues.apache.org/jira/browse/YARN-3671?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15436536#comment-15436536
] 

Jian He commented on YARN-3671:
-------------------------------

- we already have RM_CLUSTER_ID, any chance that this can be used for FEDERATION_SUBCLUSTER_ID
?
- This null check is unnecessary.
{code}
federationStateStoreService = createFederationStateStoreService();

if (federationStateStoreService != null) {
{code}
- I feel the SubClusterState is a bit redundant in the request object, because the API itself
already indicates the state such as register / deregister 
- why you need to call reinitialize ? 
{code}
public void setStateStoreClient(FederationStateStore stateStore) {
  
this.stateStoreClient = stateStore;
 
 reInitialize();

}
{code}
