Allow Super user access only from certian trusted IP Range- This is to avoid spoofing by others as super user and gain access to the cluster
--------------------------------------------------------------------------------------------------------------------------------------------

Key: HADOOP-6187
URL: https://issues.apache.org/jira/browse/HADOOP-6187
Project: Hadoop Common
Issue Type: New Feature
Components: ipc
Affects Versions: 0.20.0
Reporter: Pallavi Palleti


The current hadoop environment assumes that everything is trusted environment and so doesn't have any security checks. This might lead to any one to spoof as super user and gain access to the cluster if the environment is open for every one. So, there is a need to restrict super user permission only from certain IP addresses.
