> 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.
