             Summary: When using TIMESTAMP column as a partition key, Tajo need 
to keep keep the original TIMESTAMP values.
                 Key: TAJO-1925
                 URL: https://issues.apache.org/jira/browse/TAJO-1925
             Project: Tajo
          Issue Type: Bug
          Components: Catalog, Physical Operator
    Affects Versions: 0.11.0, 0.12.0
            Reporter: Jaehwa Jung
            Priority: Critical
             Fix For: 0.12.0, 0.11.1


Currently, Tajo allow to use TIMESTAMP column as a partition key. But if users 
use TIMESTAMP partition column, Tajo doesn't keep the original TIMESTAMP 
values. Actually, Tajo automatically converts TIMESTAMP values to STRING 
literals which are accepted in the format YYYY-MM-DD HH:MM:SS. As a result, 
Tajo can't keep mills of second and can't provide right hive compatibility
