spring boot 整合hadoop 3.1.1 报错 BlockSender.sendChunks()

Question

在spirng controller 里获取hadoop文件内容时，hadoop 服务批量报错

ERROR datanode.DataNode: BlockSender.sendChunks() exception:
java.io.IOException: 你的主机中的软件中止了一个已建立的连接。

bean

    @Bean
    public FileSystem fileSystem() throws URISyntaxException, IOException {

        URI uri = new URI("hdfs://127.0.0.1:9000");
        Configuration configuration = new Configuration();
        return FileSystem.get(uri,configuration);
    }

controller代码

    FSDataInputStream fsDataInputStream = fileSystem.open(new Path("/1.mp4"));
    byte [] a = new byte[20];
    fsDataInputStream.read(a);
    fsDataInputStream.close();   

controller代码不会报错，我试过断点调试，调试的慢，不会报错。调试的快(跳过spring框架代码)就会出错。
我写过单独main方法也试了，不管怎么读取和关闭都不会报错。是不是spring框架哪里没配置好？
