Hi. why not try iptablesJ ,which in fact with no relation with hadoop. Add all hadoop nodes and client in whitelist,add XX to blacklist if only as you will “ stop the specified client computer OS to connect hadoop”,simply create one iptable rule.
For long time planning,Kerberos is a must.

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 ? _____ 麦树荣
