从s3向athena导入数据会导致一个表，每个单元格都包含双引号。
是否有不启用双引号的特定属性？

CREATE EXTERNAL TABLE t1.test(
col_1 varchar(100),
col_2 varchar(100),
col_3 varchar(100),
col_4   varchar(100)
)
ROW FORMAT DELIMITED
     FIELDS TERMINATED BY ','
     ESCAPED BY '\\'
     LINES TERMINATED BY '\n'
LOCATION 's3://aws-athena-query-results/test/'
TBLPROPERTIES  ('skip.header.line.count'='1');
