DN中日志如下：

2017-06-17 06:35:59,242 WARN org.apache.hadoop.hdfs.server.datanode.DataNode: Problem connecting to server: node1/192.168.1.128:9000

赖自己刚把/etc/hosts改成

127.0.0.1   localhost node1 localhost4 localhost4.localdomain4

192.168.1.128 node1

原来是

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

192.168.1.128 node1
