Subject [jira] [Commented] (YARN-967) [YARN-321] Command Line Interface(CLI) for Reading Application History Storage Data
Date Mon, 25 Nov 2013 19:00:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-967?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13831776#comment-13831776
] 

Zhijie Shen commented on YARN-967:
----------------------------------

bq. Also, if a user uses YarnClient, he/she shouldn't even know about AHSClient? In a way,
YarnClient should explicitly compose AHSClient and redirect APIs accordingly. In that case,
CLI etc shouldn't even have any changes?

It's a different level of transparence. The patch ensures the redirecting to ASH transparent
to users who use CLI. Vinod's suggestion ensures it transparent to users who use either CLI
or YarnClient programmatically. It sounds better. One concern about it  is whether there exists
the case that YarnClient wants to know RMContext applications only with those in AHS excluded?

Anyway, CLI needs to be changed to support query for attempt and container.
