I cannot understand what you mean. I didn't make a directory of empty
string.
Anyway, this is the case when the partition directory doesn't contain any
data file. So this is not a problem.
After adding a data file, everything works well.
> Disable partition pruning using catalog temporarily.

> Components: Catalog, Physical Operator, Planner/Optimizer
> Affects Versions: 0.11.0, 0.12.0
> Reporter: Jaehwa Jung

> Priority: Critical
> Fix For: 0.11.0

> We disabled alter table add partition temporarily at TAJO-1887. But when
> adding partitions with dfs command for external partitioned table, there is
> no way to add partition to catalog. As a result, users can't scan their
> partitions which are added manually to file system. So, we need to disable
> partition pruning using catalog until implement TAJO-1891.
