hadoop2.6.0集群格式化后，提示DFS使用为0，剩余也为0

集群中的namenode ，datanode 都能够正常启动。不知是什么原因？？

HDFS：50070页面如下：

namenode 日志如下：（并没有error）

我发现是datanode无法连接到namenode上？？？这个怎么解决呢？
DataNode的日志信息如下：
DataNode: Problem connecting to server: controller/192.168.1.186:9000
2015-05-01 08:39:12,273 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: controller/192.168.1.186:9000. Already tried 0 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS)

确保所有进程都在，不会存在僵死进程解决办法：
重启hadoop


查看hosts,确保注释掉127.0.1.1


更多原因看
hadoop2.7 运行wordcount

解决了，是/etc/hosts文件出了问题，感谢啊。
