[jira] [Created] (HDFS-5117) Allow the owner of an HDFS path to be
a group
Ryan Hennig created HDFS-5117:
---------------------------------
Summary: Allow the owner of an HDFS path to be a group
Key: HDFS-5117
URL: https://issues.apache.org/jira/browse/HDFS-5117
Project: Hadoop HDFS
Issue Type: New Feature
Components: hdfs-client
Reporter: Ryan Hennig
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.
