我正在尝试对我的 flink 应用程序运行集成测试。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");
}
}
在这里，我从一个子线程启动我的 flink 应用程序，并上传一个文件从主线程进行处理。测试运行良好，我得到了预期的结果文件。 但是，当应用程序关闭时，我最后收到以下错误：

这里 CsvProcessorFlinkDriver.java：132 是executionResult = env.execute行。
我做错了什么吗？我还注意到，如果我在测试类的主线程(而不是从子线程(启动 flink 应用程序，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，该测试也会给出相同的错误。
当 flink 作业结束时，flink 会卸载代码使用的类。
如果在 flink 卸载它们后尝试使用这些类，您通常最终会得到ClassNotFound异常。因此，您必须确保没有代码触及这些类。
在您的情况下，您会在类org.apache.commons.io.IOUtils上获得NoSuchMethodError。似乎您使用了不同版本的commons-io，并且JettyServerFileSource尝试自动关闭某些资源。
查看您是否对commons-io的依赖与版本 2.4 不同(这是 flink 使用的版本(
