但是即使开启了所有可能的端口,但是在向Hive中插入数据时,依然报错提示:Call From hadoop01/172.23.238.2 to hadoop01:10020 failed on connection exception。这里提示从hadoop01/172.23.238.2到hadoop01:10020的调用在连接异常时失败,但是hadoop01/172.23.238.2和hadoop01是同一台服务器,连接拒绝真的令人费解。 解决办...

对于学习的过程来说,报错是一个不容跳过的步骤,把遇到的问题记录下来,以后遇到了也可以回来查看,本文章长期更新。 Q:Call From node1/192.168.200.11 to node1:9000 failed on connection exception? 今天启动了Hadoop集群之后,发现输入hdfs dfs -ls / 命令,居然出现以上报错。
