Benoy Antony commented on HADOOP-10565: --------------------------------------- Thanks [~arpitagarwal]. Were there any update ? > Support IP ranges (CIDR) in proxyuser.hosts > -------------------------------------------- > > Key: HADOOP-10565 > URL: https://issues.apache.org/jira/browse/HADOOP-10565 > Project: Hadoop Common > Issue Type: Sub-task > Components: security > Reporter: Benoy Antony > Assignee: Benoy Antony > Attachments: HADOOP-10565.patch, HADOOP-10565.patch > > > 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 we enable proxyuser.hosts to accept ip ranges in > CIDR format. > In addition, the current ip authorization involve a liner scan of the ips and > an attempt to do InetAddress.getByName() for each ip/host. > It may be beneficial to group this functionality of ip authorization by > looking up "ip addresses/host names/ip-ranges" into a separate class. This > could be reused in other usecases which require similar functionality -- This message was sent by Atlassian JIRA (v6.2#6252)
