将 Hive 查询结果输出为 csv 并用引号括起来

我必须从 csv 文件中的配置单元表导出数据，其中字段用双引号引起来。

到目前为止，我可以使用以下查询生成不带引号的 csv

INSERT OVERWRITE DIRECTORY '/user/vikas/output'
ROW FORMAT DELIMITED 
FIELDS TERMINATED BY ','
SELECT QUERY

生成的输出看起来像

1,Vikas Saxena,Banking,JL5

但是，我需要输出为

"1","Vikas Saxena","Banking","JL5" 

我尝试将查询更改为

INSERT OVERWRITE DIRECTORY '/user/vikas/output'
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
WITH SERDEPROPERTIES (
   "separatorChar" = ",",
   "quoteChar"     = "\"",
   "escapeChar"    = "\\"
)
SELECT QUERY

但它显示错误

Error while compiling statement: FAILED: ParseException line 1:0 cannot recognize input near 'ROW' 'FORMAT' 'SERDE'

创建外部表：

CREATE EXTERNAL TABLE new_table(field1 type1, ...)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
WITH SERDEPROPERTIES (
"separatorChar" = ",",
"quoteChar" = "\""
)
STORED AS TEXTFILE
LOCATION '/user/vikas/output';

然后选择该表：

insert into new_table select * from original_table;

然后，您的 CSV 位于磁盘上的 /user/vikas/output
