Subject [jira] [Commented] (YARN-78) Change UnmanagedAMLauncher to use YarnClientImpl
Date Tue, 04 Sep 2012 22:41:08 GMT

    [ https://issues.apache.org/jira/browse/YARN-78?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13448137#comment-13448137

Bikas Saha commented on YARN-78:
--------------------------------

I had given a thought to this and decided not to do it. This is because I see the launcher
evolve from being just a client to the RM. I uses the client-RM  protocol to negotiate app
launch but then goes on to provide more functionality - eg launching the actual app locally.
More can be added later. So I view the client-AM functionality as something used by the launcher
and so I included it as a member object that provides the functionality.
