Taraka Rama Rao Lethavadla created HIVE-25150:
-------------------------------------------------
Summary: Tab characters are not removed before decimal conversion
similar to space character which is fixed as part of HIVE-24378
Key: HIVE-25150
URL: https://issues.apache.org/jira/browse/HIVE-25150
Project: Hive
Issue Type: Bug
Components: Hive
Affects Versions: 4.0.0
Reporter: Taraka Rama Rao Lethavadla
Test case:
column values with space and tab character
bash-4.2$ cat data/files/test_dec_space.csv
1,0
2, 1
3, 2
{noformat}
create external table test_dec_space (id int, value decimal) ROW FORMAT
DELIMITED
FIELDS TERMINATED BY ',' location '/tmp/test_dec_space';
{noformat}
output of select * from test_dec_space would be
{noformat}
1 0
2 1
3 NULL{noformat}
The behaviour in MySQL when there is tab & space characters in decimal values
bash-4.2$ cat /tmp/insert.csv
"1","aa",11.88
"2","bb", 99.88
"4","dd", 209.88
MariaDB [test]> load data local infile '/tmp/insert.csv' into table t2 fields
terminated by ',' ENCLOSED BY '"' LINES TERMINATED BY '\n';
Query OK, 3 rows affected, 3 warnings (0.00 sec)
Records: 3 Deleted: 0 Skipped: 0 Warnings: 3
MariaDB [test]> select * from t2;
+------+------+-------+
| id | name | score |
+------+------+-------+
| 1 | aa | 12 |
| 2 | bb | 100 |
| 4 | dd | 210 |
+------+------+-------+
3 rows in set (0.00 sec)
So hive should not show up NULL
