在配置完上面的配置文件，启动后报如下错误

Using privileged resources in combination with SASL RPC data transfer protection is not supported.显示privileged resources（即小端口号）和SASL RPC data transfer protection不能同时使用。
这时候有两条道路选择：

继续使用小端口号。这样需要在root用户下使用jscv来启动dataNode，并且需要繁琐的下载依赖包额编译工作来获得jscv,最终放弃
使用大的端口号。参考： CSDN博Using privileged resources in combination with SASL RPC data transfer protection is not supported. –

这时候又报错：

这需要配置HTTPS。
参考：HDFS的HTTPS配置
