Question

我们在使用java REST客户端将jar上传到Flink 1.5.0服务器时收到错误响应{＆＃34;错误＆＃34;：[＆＃34;内部服务器错误：null＆＃34;]}。相同的代码在Flink 1.4.2中正常工作。实际上我们可以看到jar已经从Flink GUI上传了。但错误的地位打破了逻辑。有什么建议吗？

        HttpPost uploadFile = new HttpPost(flinkJobManagerUrl + "/jars/upload");
        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.addBinaryBody(
                "jarfile",
                new FileInputStream(f),
                ContentType.create("application/x-java-archive"),
                f.getName()
        );

        HttpEntity multipart = builder.build();
        uploadFile.setEntity(multipart);
        CloseableHttpResponse response = restClient.execute(uploadFile);
        rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

但过了一段时间，你会看到从GUI上传的jar。但是当它运行时它会给出另一个例外：

Answer 1

第一个例外是由于FileUploadHandler中的错误;它没有正确处理EmptyLastHttpContent消息。请参阅https://issues.apache.org/jira/browse/FLINK-9500。

第二个例外是由于程序参数中有空格而引起的，从1.5开始不再支持。

Answer 2

关于第二个异常，您可以将带有逗号的programArgs放入发布请求正文中，例如

{
  "programArgs":"--test=a,b"
}

无法使用java rest client
