> Project: Tajo

> Components: Physical Operator, Planner/Optimizer
> Reporter: Jaehwa Jung
> Assignee: Jaehwa Jung
> Fix For: 0.12.0, 0.11.1

>
> Currently, Tajo just allow well-defined partition path which includes all
> partition columns because rewriter builds basic tuple for scanning data files
> using partition path. So, if users data already exist on arbitrary partition
> path, they should move their partitions to other directories. It seems a very
> inefficient way and we need to allow arbitrary partition path.
