Subject [jira] [Commented] (YARN-103) Add a yarn AM - RM client module
Date Tue, 18 Dec 2012 17:00:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-103?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13535045#comment-13535045

Tom White commented on YARN-103:
--------------------------------

> +1, this is really helpful if we can get the APIs right.

I agree this would be very useful. Regarding getting the APIs right, making AMRMClient a class
rather than an interface would permit us to add methods later on, which is not possible for
interfaces. This is a helper class, so there shouldn't be a need for alternative implementations.

> Add a basic client wrapper library to the AM RM protocol in order to prevent proliferation
of code being duplicated everywhere. Provide helper functions to perform reverse mapping of
container requests to RM allocation resource request table format.
