Maryann Xue commented on PHOENIX-3394:
--------------------------------------

With a "connectionless" Phoenix Connection, actually you can't execute "select 
... from t" queries. You can either run an "explain" query or prepare this 
query without executing it. Like [~jamestaylor] said, "the non IT unit tests 
that run during mvn package (i.e. those derived from 
BaseConnectionlessQueryTest) do not spin up an HBase mini cluster. They are 
meant to run only compilation but perform no execution."

> Fix getHTable unsupported operation
