> 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.
