[jira] [Commented] (HADOOP-10565) Support IP ranges (CIDR) in
proxyuser.hosts
[ https://issues.apache.org/jira/browse/HADOOP-10565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13987431#comment-13987431 ]
Benoy Antony commented on HADOOP-10565:
---------------------------------------
This patch delegates the ProxyUsers's ip/host name handling to MachineList.
MachineList does ip and host lookup faster. It also enables ability to specify ip ranges in CIDR format.

> In some use cases, there will be many hosts from which the user can impersonate.
> This requires specifying many ips in the XML configuration.
> It is cumbersome to specify and maintain long list of ips in proxyuser.hosts
> The problem can be solved if proxyuser.hosts accept ip ranges in CIDR format.
