> When inserting empty data into a partitioned table, existing data would be 
> removed. Tajo provides column value partition which is hive-style partition. 
> In hive, when inserting empty data into a partition, there are two cases. If 
> you use dynamic partitions, existing data never would be removed. But if you 
> don't use dynamic partitions, existing data would be removed. When inserting 
> a data to partition, tajo user don't specify each column and each column 
> value. So, it is similar to dynamic partition of hive. It seems to update 
> deletion logic of partitioned table.
