Values inserted in hive table with double quotes f

问题:

I am exporting a csv file into hive table. about the csv file : column values are enclosed within double-quotes , seperated by comma .

Sample record from csv

"4","good"
"3","not bad"
"1","very worst"

I created a hive table with the following statement,

create external table currys(review_rating string,review_comment string ) row format fields delimited by ',';

Table created .

now I loaded the data using the command load data local inpath and it was successful. when I query the table,

select * from currys;

The result is :

"4"  "good"
"3"  "not bad"
"1"   "very worst"

instead of

4  good
3  not bad
1  very worst

records are inserted with double-quotes which shouldnt be.

Please let me know how to get rid of this double quote .. any help or guidance is highly appreciated...

Thanks beforehand!

Are you using any serde? If so, then you can write a regex command in the SERDE PROPERTIES to remove the quotes.

Or you can use the csv-serde from here and define the quote character.
