Taraka Rama Rao Lethavadla updated HIVE-25150:
----------------------------------------------
Description:
Test case:
column values with space and tab character
{noformat}
bash-4.2$ cat data/files/test_dec_space.csv
1,0
2, 1
3, 2{noformat}
{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
{noformat}
bash-4.2$ cat /tmp/insert.csv
"1","aa",11.88
"2","bb", 99.88
"4","dd", 209.88{noformat}
{noformat}
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)
{noformat}
So hive should not show up NULL
