Subject [jira] Resolved: (HADOOP-4851) Change filesystem permissions to use JAAS rather than UGI
Date Mon, 02 Aug 2010 05:20:17 GMT

]

Owen O'Malley resolved HADOOP-4851.
-----------------------------------

    Resolution: Won't Fix

I don't think this is a good idea. Having implemented on top of the JAAS stuff, the impedance
mismatch is pretty annoying. Can I close this as won't fix?

> Hadoop embraced JAAS via HADOOP-4348.
> We need to fix HDFS to use JAAS concepts such as Subject, Principal, Permission etc.
rather than UserGroupInformation for file-system permissions.
