bq.  YARN-3409 Wouldn't be a blocker since this JIRA is a improvement of YARN-6507.
I'm not sure how to support device meta info in global (RM) scheduler without YARN-3409, I couldn't find the answer from attached design doc. Could you explain what is the solution in your mind?

Anyway I'm in favor of using a general approach which can be utilized by other features instead of customize RM scheduler to support FPGA requirements. GPU support is more sensitive to GPU type instead of firmware, but I can see docker support can be improved a lot if we can schedule containers to a node which already has localized docker image.

> In order to provide a global optimal scheduling for mutable FPGA resource, it seems an easy and direct way to utilize constraint node labels(YARN-3409) instead of extending the global scheduler(YARN-3926) to match both resource count and attributes.
> The rough idea is that the AM sets the constraint node label expression to request containers on the nodes whose FPGA devices has the matching IP, and then NM resource handler update the node constraint label if there's FPGA device re-configuration.
