-------------------------------------
Summary: Support mapping Spark gpu/fpga resource types to custom
YARN resource type
Key: SPARK-37208
URL: https://issues.apache.org/jira/browse/SPARK-37208
Project: Spark
Issue Type: Improvement
Components: YARN
Affects Versions: 3.0.0
Reporter: Thomas Graves
Currently Spark supports gpu/fpga resource scheduling and specifically on YARN
it knows how to map gpu/fpga to the YARN resource types yarn.io/gpu and
yarn.io/fpga. YARN also supports custom resource types and in Hadoop 3.3.1
made it easier for users to plugin in custom resource types. This means users
may create a custom resource type that represents a GPU or FPGAs because they
want additional logic that YARN the built in versions don't have. Ideally Spark
users still just use the generic "gpu" or "fpga" types in Spark. So we should
add the ability to change the Spark internal mappings.
