@Test

	Assert.assertFalse(checkpointConfig.isFailOnCheckpointingErrors());
	Assert.assertEquals(CheckpointFailureManager.UNLIMITED_TOLERABLE_FAILURE_NUMBER, checkpointConfig.getTolerableCheckpointFailureNumber());

	// use new API to set tolerable declined checkpoint number
	checkpointConfig.setTolerableCheckpointFailureNumber(5);
	Assert.assertEquals(5, checkpointConfig.getTolerableCheckpointFailureNumber());

	// after we configure the tolerable declined checkpoint number, deprecated API would not take effect
	checkpointConfig.setFailOnCheckpointingErrors(true);
