Project: Tajo
Issue Type: Bug
Components: Data Type, Storage, Unit Test
Affects Versions: 0.12.0
Reporter: Jinho Kim
Assignee: Jinho Kim
Priority: Critical
Currently, Most DateTime tests are not work correctly. because timezone is
hardcode to the GMT for testing.
if you run CTAS, the result data will be incorrect. we should remove the
hardcoded timezone in TajoTestingCluster
Here is some examples:
Example 1
{noformat}
if you run CTAS, the result data will be incorrect
default> create table test1 (col1 TIMESTAMP);
default> insert overwrite into test1 select '2016-04-04 00:00:00'::TIMESTAMP;
default> select * from test1;
col1
-------------------------------
2016-04-04 00:00:00
(1 rows, 0.057 sec, 0 B selected)
default> create table test2 as select * from test1;
[=========================================>] 100% 0.105 sec
(1 rows, 0.105 sec, 20 B inserted)
default> select * from test2;
col1
-------------------------------
2016-04-03 15:00:00
{noformat}
Example 2
{noformat}
default> select '2016-04-04 01:00:00'::TIMESTAMP - interval '1 hour';
