Wangda Tan commented on YARN-9087:
----------------------------------
[~snemeth], Device plugin framework is for the future plugins. We won't
"deprecate" existing GPU implementation. But I can expect once device plugin
framework becomes ready, we can do refactoring to make better code structure
and more maintainable.
The nvidia-docker-plugin has two versions, v1 and v2. As of now, we're using v1
nvidia-docker-plugin, which is deprecated by nvidia. There's a patch to support
v2 plugin. (YARN-8822). Same to existing GPU implementation, once device plugin
framework becomes ready, we will refactor the code to use that if efforts are
reasonable.
> Better logging for initialization of Resource plugins
