Date Wed, 13 Sep 2017 04:51:02 GMT

    [ https://issues.apache.org/jira/browse/YARN-6852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16164150#comment-16164150

Zhankun Tang commented on YARN-6852:
------------------------------------

[~wangda], Yeah.  At present, all supported resource type needs to committed to YARN as first-class
citizen. 

I'm not quite sure if it's easy to do but trying to find a way to improve current framework
to support a new set of devices resource like GPU, FPGA, sound card, SSD, etc with  plugins
that don't needs to change YARN core.
I don't have a clear picture in my mind at present. Never mind, just some thoughts wants to
share after reviewing kubernetes' in-progress plugin design on [hardware-accelerator|https://github.com/kubernetes/community/pull/844]
and [device-manager|https://github.com/kubernetes/community/blob/master/contributors/design-proposals/device-plugin.md].
