Resource model in Hadoop 3 allows us to define custom resource types. I did some googling but couldn't find anything that would tell how can the YARN FairScheduler be configured to distribute/isolate these resources among its pools.

Found JIRA [Umbrella] YARN Resource Profiles phase#2 enhancements, with some sub-tasks related to RM UI- and inner workings of the FairScheduler, e.g. "Add support for dynamic resource updates with multiple resource types". As of July 2019, some of the sub-tasks are still open.
