--------------------------------

             Summary: Print expected values when rejecting a server's determined principal
                 Key: HADOOP-13056
                 URL: https://issues.apache.org/jira/browse/HADOOP-13056
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 2.5.0
            Reporter: Harsh J
            Assignee: Harsh J
            Priority: Trivial


When an address-constructed service principal by a client does not match a provided pattern or the configured principal property, the error is very uninformative on what the specific cause is. Currently the only error printed is, in both cases:

{code}
 java.lang.IllegalArgumentException: Server has invalid Kerberos principal: hdfs/host.internal@REALM
{code}
