A Hive Table Partition: is a fundamental storage unit within a Table. Currently, Hive does not support
hierarchical partitions - For eg: if partition ds=1, hr=1 exists, there is no way to access ds=1

Hierarchical partitions are needed in some cases, for eg. locking. For now, create a dummy partition to
satisfy this
