搭建好hadoop后使用hadoop dfs -put 命令上传文件发现失败，报了以下错误：

看它的报错信息好像是节点没有启动，但是我的节点都启动起来了，使用jps也能查看到节点信息。  
使用hadoop dfsadmin -report命令查看磁盘使用情况，发现出现以下问题：

[java] view plain copy
    Configured Capacity: 0 (0 B)  
    Present Capacity: 0 (0 B)  
    DFS Remaining: 0 (0 B)  
    DFS Used: 0 (0 B)  
    DFS Used%: NaN%  
    Under replicated blocks: 0  
    Blocks with corrupt replicas: 0  
    Missing blocks: 0  
    ------------------------------------------------- 
    Datanodes available: 0 (0 total, 0 dead)

节点下存储空间都是空的，问题应该就是出现在这了。  
查阅资料发现造成这个问题的原因可能是使用hadoop namenode -format格式化时格式化了多次造成那么spaceID不一致，解决方案：

1、停止集群（切换到/sbin目录下）  
$./stop-all.sh

2、删除在hdfs中配置的data目录（即在core-site.xml中配置的hadoop.tmp.dir对应文件件）下面的所有数据;  
$ rm -rf /home/hadoop/hdpdata/\*

3、重新格式化namenode(切换到hadoop目录下的bin目录下)  
$ ./hadoop namenode -format

4、重新启动hadoop集群（切换到hadoop目录下的sbin目录下）  
$./start-all.sh

在使用hadoop dfsadmin -report查看使用情况，结果如下图所示：

ok没有错误了。再次上传文件，成功。
