All the three partitions point reside under the same base dir. In reality
it might be possible that all three are pointing to different locations. You
could simulate that by creating empty partition (`ALTER TABLE ... ADD
PARTITION`), then doing a `ALTER TABLE table_name [PARTITION partition_spec]
SET LOCATION "new location"` and finally inserting data to the partition.
