[jira] [Updated] (HIVE-25150) Tab characters are not removed before decimal conversion similar to space character which is fixed as part of HIVE-24378

     [ https://issues.apache.org/jira/browse/HIVE-25150?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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
 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
