  1. Currently, only ORC storage format is supported. So 'stored as orc' must be specified during table creation.
  2. The Hive table must be bucketed, but not sorted. So something like 'clustered by (colName) into 10 buckets' must be specified during table creation. See Bucketed Tables for a detailed example.
