The kerberos RPC does not declare any restriction on characters used in kerberos names, though implementations MAY be more restrictive. If the kerberos controller supports use non-conventional principal names *and the kerberos admin chooses to use them* this can confuse some of the parsing. The obvious solution is for the enterprise admins to "not do that" as a lot of things break, bits of hadoop included. Harden the hadoop code slightly so at least we fail more gracefully, so people can then get in touch with their sysadmin and tell them to stop it. ### How was this patch tested? ### For code changes: - [ ] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799.
