             Summary: HCatalogStore can't write any data using INSERT OVERWRITE clause
                 Key: TAJO-431
                 URL: https://issues.apache.org/jira/browse/TAJO-431
             Project: Tajo
          Issue Type: Bug
    Affects Versions: 0.8-incubating
            Reporter: JaeHwa Jung
            Assignee: JaeHwa Jung
             Fix For: 0.8-incubating


If I write INSERT OVERWRITE INTO clause using HCatalogStore, HCatalogStore can't write any
data even though scan table has data. I found this bug as follows :

{code:title=scan table |borderStyle=solid}
