> [~stoty] found that we aren't doing {{_HOST}} expansion for PQS. We naturally
> get this for the principal we use to talk to HBase (by virtue of using
> SecurityUtil/UGI to log in). However, for SPNEGO, we're using the Avatica API
> to do this, so it doesn't do this "Hadoop-ism" for us.
> We can use SecurityUtil to do it ourselves and then pass the correct hostname
> into the Avatica {{HttpServer.Builder}} API.
> The error you get when {{_HOST}} is set is pretty obtuse on the server-side,
> including to help the poor soul who ventures here with a similar error.
