搞了几天都没有解决，所以来求助了……

1.首先检查：checkpoint是否存在了相同的路径
2.balancer命令是否在多处执行

easthome001 发表于 2016-6-4 16:32:16

hdfs://dlhtHadoop101:8022
hdfs://dlhtHadoop101:8020

这两个应该冲突了

1.首先检查：checkpoint是否存在了相同的路径
2.balancer命令是否在多处执行非常感谢

1.首先检查：checkpoint是否存在了相同的路径
你说checkpoint哪个路径的文件哈？

2.balancer命令是否在多处执行

我每个节点都ps -aux | grep balancer 了，都没有发现执行的节点。。

hdfs://dlhtHadoop101:8022
hdfs://dlhtHadoop101:8020

我刚才查了这两个端口对应的进程，一个是namenode，一个是datanode……

我将这台机子的DataNode下线了。。。依然balancer时还报这个问题

配置肯定有问题的，不可能存在两种访问方式
hdfs://dlhtHadoop101:8022
hdfs://dlhtHadoop101:8020

我看了以前balancer正常的日志，当时就是这样的两个节点……
这个配置应该是修改哪里的呢？我找了没有找到。。。。。
