Example 7 with LeafQueue

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

the class TestWorkPreservingRMRestart method testCapacitySchedulerRecovery.

// Test CS recovery with multi-level queues and multi-users:
// 1. setup 2 NMs each with 8GB memory;
// 2. setup 2 level queues: Default -> (QueueA, QueueB)
// 3. User1 submits 2 apps on QueueA
// 4. User2 submits 1 app  on QueueB
// 5. AM and each container has 1GB memory
// 6. Restart RM.
// 7. nm1 re-syncs back containers belong to user1
// 8. nm2 re-syncs back containers belong to user2.
// 9. Assert the parent queue and 2 leaf queues state and the metrics.
// 10. Assert each user's consumption inside the queue.
