Hey, A few weeks ago I proposed an abstraction for the IP address. There has been a long discussion on how to implement this (eg: what kind of pattern to use, composition/inheritance).
Ben Hindman proposed a replacement of the Node class with Address and moving several network functions to the network namespace, which affects my implementation[1]. Here are my code reviews[2] and the Jira discussion on this issue[3]. To speed up the review process, we decided to move this discussion of the dev mailing list so anyone can chime in. Thanks, Evelina [1] https://reviews.apache.org/r/29538/ https://reviews.apache.org/r/29540/ https://reviews.apache.org/r/29541/ [2] https://reviews.apache.org/r/29288/ https://reviews.apache.org/r/29289/ https://reviews.apache.org/r/29290/ [3] https://issues.apache.org/jira/browse/MESOS-1919
