我正在teradata prestodb发行版中为hive运行一个查询 catalog 作为：

CREATE EXTERNAL TABLE hive.default.mydata
id INT, datetime timestamp, latitude FLOAT,
longitude FLOAT, bookingid VARCHAR, pre_lat FLOAT,
pre_long FLOAT, time_hour decimal(6, 1), dist_kms decimal(6, 1),
ma6_dist_kms decimal(6, 1), istationary INT, quality_overall VARCHAR,
quality_nonstationary VARCHAR, cartype VARCHAR, isbigloss INT,
bookregion VARCHAR, iho_road VARCHAR)
STORED AS PARQUET
LOCATION "s3://sb.mycompany.com/someFolder/anotherFolder";

引发以下异常：

Query 20180316_022346_00001_h9iie failed: line 1:8: no viable alternative at input 'CREATE EXTERNAL'

即使使用配置单元并运行show table命令，在设置了架构但未设置目录时也会看到错误：

presto> use hive;
presto:hive> show tables;
Error running command:
Error starting query at http://localhost:8080/v1/statement returned HTTP response code 400.
Response info:
JsonResponse{statusCode=400, statusMessage=Bad Request, headers={Content-Length=[32], Date=[Fri, 16 Mar 2018 02:25:25 GMT], Content-Type=[text/plain]}, hasValue=false, value=null}
Response body:
Schema is set but catalog is not

任何帮助都将不胜感激。谢谢。
