  16. def requests: Map[String, TaskResourceRequest]

    Returns all the resource requests for the task.

  17. def requestsJMap: Map[String, TaskResourceRequest]

    (Java-specific) Returns all the resource requests for the task.

  18. def resource(resourceName: String, amount: Double): TaskResourceRequests.this.type

    Amount of a particular custom resource(GPU, FPGA, etc) to use.

    Amount of a particular custom resource(GPU, FPGA, etc) to use. This is a convenient API to add TaskResourceRequest for custom resources.

    resourceName

    Name of the resource.

    amount

    Amount requesting as a Double to support fractional resource requests. Valid values are less than or equal to 0.5 or whole numbers. This essentially lets you configure X number of tasks to run on a single resource, ie amount equals 0.5 translates into 2 tasks per resource address.
