今天部署2.7.1時在格式化namenode時遇到下面的錯誤

省略前面部分.......
16/10/26 18:32:45 ERROR namenode.NameNode: Failed to start namenode.

錯誤配置：

<property>
	<name>dfs.namenode.name.dir</name>
	<value>file://data01/hadoop/dfs/name</value>
</property>

<property>
	<name>dfs.namenode.name.dir</name>
	<value>file:/data01/hadoop/dfs/name</value>
</property>
 

再次格式化namenode，成功了:
