Flink应用集成测试

Question

我正在尝试对我的flink应用程序进行集成测试。我的测试代码如下所示：

public class HttpsCsvIngestorTest extends AbstractTestBase {

    private final static Logger LOG = LoggerFactory.getLogger(HttpsCsvIngestorTest.class);

    @Test
    public void testHttpsCsvIngestion() throws Exception {

        Thread flinkJob = new Thread(new Runnable() {
            @Override
            public void run() {
                String[] args = new String[] { "--configFile", "the/path/to/config.properties", "--secretKey",
                        "12345" };
                JobExecutionResult execResult = CsvProcessorFlinkDriver.runFlinkJob(args);
            }
        });

        flinkJob.start();
        LOG.info("Starting flink job");

        Thread.sleep(10000);
        String[] args2 = new String[] { "localhost", filename }; 
        FileUploadClient.main(args2);

        Thread.sleep(30000);
        assertTrue(new File(System.getProperty("user.dir") + File.separator + "C:/Desktop/Result.csv")
                .exists());
        System.out.println("Test completed. Going to shutdown flink job");
    }

}

这里，我从一个子线程启动我的flink应用程序，并从主线程上传一个用于处理的文件。测试运行良好，我得到了预期的结果文件。但是，当应用程序被关闭时，在结束时我会得到以下错误：

这里CsvProcessorFlinkDriver.java:132是executionResult = env.execute行。

我做错什么了吗？我还注意到，如果我在测试类的主线程中启动flink应用程序(而不是从子线程启动)，则执行不会进展到从LOG.info开始的行(“启动flink作业”)；

我的flink版本是1.5.0。即使使用flink-1.6.0，测试也会产生相同的误差。

Answer 1

当flink作业结束时，代码使用的flink 卸货类。

如果在flink卸载这些类之后，有什么东西试图使用这些类，那么通常会出现ClassNotFound异常。因此，您必须确保没有任何代码接触到这些类。

在您的例子中，您可以在类NoSuchMethodError上得到一个org.apache.commons.io.IOUtils。似乎您使用了一个不同版本的公域-io和JettyServerFileSource试图AutoClose一些资源。

查看您是否依赖于与版本2.4不同的commons-io (这是flink使用的版本)
