Subject how to stop the specified client computer OS to connect hadoop using super user
Date Fri, 24 May 2013 09:27:51 GMT
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 ?
