[jira] [Created] (HADOOP-11628) SPNEGO auth does not work with CNAMEs in JDK8

Daryn Sharp created HADOOP-11628:
------------------------------------

             Summary: SPNEGO auth does not work with CNAMEs in JDK8
                 Key: HADOOP-11628
                 URL: https://issues.apache.org/jira/browse/HADOOP-11628
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 2.6.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp
            Priority: Critical


Pre-JDK8, GSSName auto-canonicalized the hostname when constructing the principal for SPNEGO.  JDK8 no longer does this which breaks the use of user-friendly CNAMEs for services.
