Thomas Graves created SPARK-27488:
-------------------------------------

             Summary: Driver interface to support GPU resources 
                 Key: SPARK-27488
                 URL: https://issues.apache.org/jira/browse/SPARK-27488
             Project: Spark
          Issue Type: Story
          Components: Spark Core
    Affects Versions: 3.0.0
            Reporter: Thomas Graves
            Assignee: Thomas Graves


We want to have an interface to allow the users on the driver to get what resources are allocated to them.  This is mostly to handle the case the cluster manager does not launch the driver in an isolated environment and where users could be sharing hosts.  For instance in standalone mode it doesn't support container isolation so a host may have 4 gpu's, but only 2 of them could be assigned to the driver.  In this case we need an interface for the cluster manager to specify what gpu's for the driver to use and an interface for the user to get the resource information
