hadoop mkdir 时 Name node is in safe mode

hadoop mkdir 时 Name node is in safe mode，但是我已经关闭了safe mode：
hdfs dfsadmin -safemode leave

执行下这条命令
[mw_shl_code=bash,true]hadoop dfsadmin -safemode leave[/mw_shl_code]

谢谢你 ，可是还是不行 配置文件hdfs.site.sh我也改了，加入<dfs.permissions.enabled>，值为false，也不可以重新格式化结点也不行

解决了，是要在hdfs-site.xml里添加
[mw_shl_code=bash,true]<property>
  <name>dfs.namenode.safemode.threshold-pct</name>
  <value>0.999f</value>
  <description>
    Specifies the percentage of blocks that should satisfy the minimal
    replication requirement defined by dfs.namenode.replication.min.
    Values less than or equal to 0 mean not to wait for any particular
    percentage of blocks before exiting safemode.
    Values greater than 1 will make safe mode permanent.
  </description>
</property>[/mw_shl_code]
