Example 11 with ContainerEvent

use of org.apache.hadoop.yarn.server.nodemanager.containermanager.container.ContainerEvent in project hadoop by apache.

the class TestResourceLocalizationService method testPublicResourceAddResourceExceptions.

/*
   * Test case for handling RejectedExecutionException and IOException which can
   * be thrown when adding public resources to the pending queue.
   * RejectedExecutionException can be thrown either due to the incoming queue
   * being full or if the ExecutorCompletionService threadpool is shutdown.
   * Since it's hard to simulate the queue being full, this test just shuts down
   * the threadpool and makes sure the exception is handled. If anything is
   * messed up the async dispatcher thread will cause a system exit causing the
   * test to fail.
