Github user merrimanr commented on the issue: https://github.com/apache/metron/pull/891 @MohanDV this is a good start and will be a nice feature to have. I have a couple suggestions. First, can we move this to it's own function/endpoint? I think this would be useful for assigning permissions to existing topics as well. Second, I think we need some kind of check that Kerberos is enabled before we try to permission a topic for a user. This would be similar to what's done in the [KafkaConfig](https://github.com/apache/metron/blob/master/metron-interface/metron-rest/src/main/java/org/apache/metron/rest/config/KafkaConfig.java) class on line 111.
