Examples with CapacitySchedulerConfiguration org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacitySchedulerConfiguration used on opensource projects

Example 1 with CapacitySchedulerConfiguration

use of org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacitySchedulerConfiguration in project hadoop by apache.

the class TestWorkPreservingRMRestart method testCapacityLeafQueueBecomesParentOnRecovery.

//Test behavior of an app if queue is changed from leaf to parent during
//recovery. Test case does following:
//1. Add an app to QueueB and start the attempt.
//2. Add 2 subqueues(QueueB1 and QueueB2) to QueueB, restart the RM, once with
//   fail fast config as false and once with fail fast as true.
//3. Verify that app was killed if fail fast is false.
//4. Verify that QueueException was thrown if fail fast is true.
