def
addRequest(treq: TaskResourceRequest): TaskResourceRequests.this.type
Add a certain TaskResourceRequest to the request set.
-
def
cpus(amount: Int): TaskResourceRequests.this.type
Specify number of cpus per Task.
Specify number of cpus per Task. This is a convenient API to add TaskResourceRequest for cpus.
- amount
Number of cpus to allocate per Task.
-
def
requests: Map[String, TaskResourceRequest]
Returns all the resource requests for the task.
-
def
requestsJMap: Map[String, TaskResourceRequest]
(Java-specific) Returns all the resource requests for the task.
-
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.
