Jim Brennan commented on HADOOP-16361:
--------------------------------------

This was fixed in trunk in HADOOP-16031, but that fix is dependent on 
HADOOP-15996.

[~eyang] commented on this in HADOOP-16031:
{quote}Jim Brennan This patch does not apply to branch-2 because:

1. When TestSecureLogins was merged, HADOOP-12751 was in branch-2.
 2. acl_to_local act as a firewall rule again after HADOOP-15959 reverted 
HADOOP-12751.
 3. acl_to_local pass through is only allowed in Hadoop 3.1.2+ by HADOOP-15996 
(new feature).

The test case does not have a way to work in branch-2 latest anymore because 
lack of ability to allow non-matching auth_to_local rule to pass through. It 
would be best to open a separate issue to address the gap because the branch-2 
KerberosName#getShortName() lacks the ability to handle complex non-kerberos 
name (zookeeper/localhost).
{quote}
Has this test always failed in branch-2?   Or did something change that caused 
it to start failing?

I don't know what the appropriate solution is here.
