             Summary: [Umbrella] A new device plugin framework to ease vendor 
plugin development
                 Key: YARN-8851
                 URL: https://issues.apache.org/jira/browse/YARN-8851
             Project: Hadoop YARN
          Issue Type: New Feature
          Components: yarn
            Reporter: Zhankun Tang
            Assignee: Zhankun Tang


At present, we support GPU/FPGA device in YARN through a native, coupling way. 
But it's difficult for a vendor to implement such a device plugin because the 
developer needs much knowledge of YARN internals. And this brings burden to the 
community to maintain both YARN core and vendor-specific code.

Here we propose a new device plugin framework to ease vendor device plugin 
development and provide a more flexible way to integrate with YARN NM.
