【大数据系列】hadoop上传文件报错_COPYING_ could only be replicated to 0 nodes

使用hadoop上传文件 hdfs dfs -put XXX

　　查看hadoop是否正常，进程是否完整

查看磁盘使用情况

从这里可以看出操盘的空间都是空的

原因可能是hadoop格式化的时候出现了问题

然后将logs和tmp中的文件全部删除，重新格式化也没成功，后来看到clusterId不一致的问题

修改了VERSION文件中的clusterId随着又出现了 is in an inconsistent state的问题，

在hadoop-hdfs.xml中增加了

<property> 
<name>dfs.name.dir</name> 
<value>/soft/hadoop/name</value> #hadoop的name目录路径     
</property> 
<property> 
<name>dfs.data.dir</name> 
<value>/soft/hadoop/data</value> #hadoop的data目录路径 
</property>
