      Description

      The following query will break Qserv:

      SELECT objectId, objectId as o1.objectId FROM Object LIMIT 1


      ERROR 4005 (Proxy) at line 1: Cannot connect to Qserv master; 
      Exception in RPC call: ...tack/Linux64/lua/5.1.4/share/lua/5.1/xmlrpc/http.lua:41:
      		 
      connection refused

      Here is what vanilla MySQL does:

      ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual
      		 
      that corresponds to your MySQL server version for the right syntax to use near 
      '.objectId FROM   Object LIMIT 1' at line 1

            This appears to no longer crash Qserv, but returns a generic ParseException. It would still be good to improve the error message with at least an indication of where the parse failed.
