Examples with DefaultScheduler org.apache.flink.runtime.scheduler.DefaultScheduler used on opensource projects

Example 6 with DefaultScheduler

use of org.apache.flink.runtime.scheduler.DefaultScheduler in project flink by apache.

the class OperatorCoordinatorSchedulerTest method createAndStartScheduler.

private DefaultScheduler createAndStartScheduler() throws Exception {
    final DefaultScheduler scheduler = setupTestJobAndScheduler(new TestingOperatorCoordinator.Provider(testOperatorId));
    scheduler.startScheduling();
    executor.triggerAll();
    // guard test assumptions: this brings tasks into DEPLOYING state
    assertEquals(ExecutionState.DEPLOYING, SchedulerTestingUtils.getExecutionState(scheduler, testVertexId, 0));
    return scheduler;
}
