      Description

      At eBay, we have the need to associate some HDFS paths with a set of users with write access, a set of users with read-only access, and neither read or write to others.

      The current model of POSIX-style permissions is nearly sufficient for this, except for the need of multiple writers.

      One easy fix would be to allow the owner of a path to be a group, and then grant owner permissions to all members of that group. I have verified that HDP 1.3 allows you to set the owner of a path to a group without error, but the owner permissions of that group are not given to members of the group.

      I've created a relatively simple fix for this by modifying the "check" method in src/hdfs/org/apache/hadoop/hdfs/server/namenode/FSPermissionChecker.java and I am working on related changes to unit tests etc now.
