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>
重新格式化然后启动就可以了。
陆陆续续折腾了一上午、、、
