主题: how to stop the specified client computer OS to connect hadoopusing super user



        hi, all
  
 Our hadoop is started by user "hadoop",and the user "hadoop" is super user. 
 Therefore, the hadoop client from other computer can manipulate HDFS using super user "hadoop" as long as the client computer OS has the user "hadoop".
  
 Are there any idea to stop the specified client computer OS to connect hadoop using super user if we don't use Kerberos ?
