> Hadoop formats delegation token services as host:port. This format is ambiguous for IPv6 literals. Update NetUtils and SecurityUtil to use bracketed IPv6 authorities. Verify round trips with hadoop.security.token.service.use_ip set to true and false. Reject ambiguous unbracketed IPv6 authorities.
