[jira] [Resolved] (YARN-1389) ApplicationClientProtocol and ApplicationHistoryProtocol should expose analog APIs

     [ https://issues.apache.org/jira/browse/YARN-1389?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Zhijie Shen resolved YARN-1389.
-------------------------------

    Resolution: Duplicate

ApplicationClientProtocol and ApplicationHistoryProtocol is going to share the common base interface (YARN-1266). Therefore, we don't need to duplicate the APIs in both protocols. Close it as duplicate.

> As we plan to have the APIs in ApplicationHistoryProtocol to expose the reports of *finished* application attempts and containers, we should do the same for ApplicationClientProtocol, which will return the reports of *running* attempts and containers.
> Later on, we can improve YarnClient to direct the query of running instance to ApplicationClientProtocol, while that of finished instance to ApplicationHistoryProtocol, making it transparent to the users.
