jiangxb1987 commented on issue #26078: [SPARK-29151][CORE] Support fractional resources for task resource scheduling URL: https://github.com/apache/spark/pull/26078#issuecomment-545439629 Thanks @tgravescs I agree it should be a useful feature, but still hesitate how much Spark shall be aware of the resource scheduling. For example, do we want to handle the failure on Spark side that sometimes one task request to use a GPU but the GPU resource is busy and need to deny the request? Should the user code be able to handle that?
