Major Description
Currently we can't restrict what networks are allowed to transfer data using WebHDFS. Obviously we can use firewalls to block ports, but this can be complicated and problematic to maintain. Additionally, because all the jetty servlets run inside the same container, blocking access to jetty to prevent WebHDFS transfers also blocks the other servlets running inside that same jetty container.
I am requesting a deny/allow feature be added to WebHDFS. This is already done with the Apache HTTPD server, and is what I'd like to see the deny/allow list modeled after. Thanks.
