Subject [jira] [Commented] (YARN-103) Add a yarn AM - RM client module
Date Wed, 19 Dec 2012 17:15:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-103?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13536147#comment-13536147

Bikas Saha commented on YARN-103:
---------------------------------

I think the patch follows the example you mention about interface and default implementation.
What I dont understand is why the default implementation should be made abstract? Noone will
be able to use a fully functional implementation if its made abstract.

> 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.
