---------------------------------

             Summary: INSERT OVERWRITE INTO should not remove all partitions.
                 Key: TAJO-1067
                 URL: https://issues.apache.org/jira/browse/TAJO-1067
             Project: Tajo
          Issue Type: Bug
          Components: query master
            Reporter: Jaehwa Jung
            Assignee: Jaehwa Jung
            Priority: Critical
             Fix For: 0.9.0


Currently, INSERT OVERWRITE INTO always moves the result data into the original 
table location. As a result, all existing partitions have been removed. The 
query should not remove all partitions because existing partitions may be a 
dataset for a production cluster.
