执行hadoop fs -mkdir /input 也会发生上边一样的错误 |

大家互动效果不错啊 在回答问题之间,简单说一下,问问题的方法,和解决问题的大致思路。 问问题的时候,最好能把实验到哪一步是正常的,哪一步开始出现的问题。 解决问题的大致思路 最后,终于。。。开始正式回答问题了 大体上的思路就是这些,其实不仅仅是这次课程的内容,可能更多时候希望能够传达一些方法论的知识,面对问题,如何拆分成更小的问题,逐个击破。 |

hdfs hdfadmin -report 发生如下错误
hadoop Protocol message tag had invalid wire type
我查了下说要改 core-site.xml或hdfs-site.xml。
这两个文件是徐老师提供的不应该有问题是不是其它那里配置不对?
