A way to do that is creating a stage table that load the file with quotes and then with CTAS (Create table as select) create the right table cleaning the fields with replace function. As an example

CREATE TABLE quote_stage(
 id STRING,
 name STRING)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ','
STORED AS TEXTFILE;

+-----+----------+
| id  | name     |
+-----+----------+
| "1" | "pepe"   |
| "2" | "ana"    |
| "3" | "maria"  |
| "4" | "ramon"  |
| "5" | "lucia"  |
| "6" | "carmen" |
| "7" | "alicia" |
| "8" | "pedro"  |
+-----+----------+

CREATE TABLE t_quote 
ROW FORMAT DELIMITED FIELDS TERMINATED BY ','
STORED AS TEXTFILE
AS SELECT replace(id,'"','') AS id, replace(name,'"','') AS name FROM quote_stage;

+----+--------+
| id | name   |
+----+--------+
| 1  | pepe   |
| 2  | ana    |
| 3  | maria  |
| 4  | ramon  |
| 5  | lucia  |
| 6  | carmen |
| 7  | alicia |
| 8  | pedro  |
+----+--------+

Hope this helps.
