Daryn Sharp commented on HDFS-12907:
------------------------------------
Minor things:
# The case statements should be indented within the switch block. It's like
writing an if or while w/o indenting the body.
# Should change the test {{testAdminAccessOnly}} to something like
{{testUserReadAccessOnly}} to reflect what it's now testing.
# There's no need to try-catch just to call Assert.fail. All it does is
swallow the exception that caused the unexpected test failure. Get rid of the
try blocks and just let the exception itself fail the test.
> Allow read-only access to reserved raw for non-superusers

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode

> HDFS-6509 added a special /.reserved/raw path prefix to access the raw file
> contents of EZ files. In the simplest sense it doesn't return the FE info in
> the {{LocatedBlocks}} so the dfs client doesn't try to decrypt the data.
> This facilitates allowing tools like distcp to copy raw bytes.
> Access to the raw hierarchy is restricted to superusers. This seems like an
> overly broad restriction designed to prevent non-admins from munging the EZ
> related xattrs. I believe we should relax the restriction to allow
> non-admins to perform read-only operations. Allowing non-superusers to
> easily read the raw bytes will be extremely useful for regular users, esp.
> for enabling webhdfs client-side encryption.
