示例1: testNoRestartingWhenCheckpointingAndExplicitExecutionRetriesZero

import org.apache.flink.streaming.api.environment.StreamExecutionEnvironment; //导入方法依赖的package包/类
/**
 * Checks that in a streaming use case where checkpointing is enabled and the number
 * of execution retries is set to 0, restarting is deactivated.
 */
@Test
public void testNoRestartingWhenCheckpointingAndExplicitExecutionRetriesZero() throws Exception {
	StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
	env.enableCheckpointing(500);
	env.setNumberOfExecutionRetries(0);

	env.fromElements(1).print();
