Subject [jira] [Commented] (YARN-983) ApplicationReport can return tokens only when users asks for it explicitly
Date Mon, 29 Jul 2013 17:49:50 GMT

    [ https://issues.apache.org/jira/browse/YARN-983?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13722721#comment-13722721

Vinod Kumar Vavilapalli commented on YARN-983:
----------------------------------------------

We don't really know when ClientToken needs to be returned. Every time a new client wishes
to talk to an AM, it needs the ClientToken.

> There is no need for ApplicationReport to always fetch client and AMtoRM Tokens (in case
of UnmanagedAMs) everytime ApplicationReport is requested. We can send it only when users
explicitly asks for it via a new field in GetApplicationReportRequest.
