Functions

func DynamicAllocationSparkPods

func DynamicAllocationSparkPods(sparkApplicationID string, minExecutors int, maxExecutors int) []v1.Pod

DynamicAllocationSparkPods returns a list of pods corresponding to a Spark Application with 1 driver and maxExecutors executors with the proper dynamic allocation annotations set for min and max executor counts

func NewNode

func NewNode(name string) v1.Node

NewNode creates a new dummy node with the given name

func StaticAllocationSparkPods

func StaticAllocationSparkPods(sparkApplicationID string, numExecutors int) []v1.Pod

StaticAllocationSparkPods returns a list of pods corresponding to a Spark Application with 1 driver and numExecutors executors with the proper static allocation annotations set

func StaticAllocationSparkPodsWithExecutorGPUs

func StaticAllocationSparkPodsWithExecutorGPUs(sparkApplicationID string, numExecutors int) []v1.Pod

StaticAllocationSparkPodsWithExecutorGPUs returns a list of pods corresponding to a Spark Application with 1 driver and numExecutors executors with the proper static allocation annotations set, executors also request one gpu

Types

}

Harness is an extension of an extender with in-memory k8s stores

func NewTestExtender

func NewTestExtender(objects ...runtime.Object) (*Harness, error)

NewTestExtender returns a new extender test harness, initialized with the provided k8s objects

func (*Harness) AssertFailedSchedule

func (h *Harness) AssertFailedSchedule(t *testing.T, pod v1.Pod, nodeNames []string, errorDetails string)

AssertFailedSchedule tries to schedule the provided pods and fails the test if successful

func (*Harness) AssertSuccessfulSchedule

func (h *Harness) AssertSuccessfulSchedule(t *testing.T, pod v1.Pod, nodeNames []string, errorDetails string)

AssertSuccessfulSchedule tries to schedule the provided pods and fails the test if not successful

func (*Harness) Schedule

func (h *Harness) Schedule(t *testing.T, pod v1.Pod, nodeNames []string) *schedulerapi.ExtenderFilterResult

Schedule calls the extender's Predicate method for the given pod and nodes

func (*Harness) TerminatePod

func (h *Harness) TerminatePod(pod v1.Pod) error

TerminatePod terminates an existing pod
