> This is particularly for the Hive storage-engine where the schema name is composed of a root followed by the storage-engine's own schema name. E.g., configuring Hive leads to a schema name "hivestg.default":
> 0: jdbc:drill:schema=hivestg> select * from INFORMATION_SCHEMA.SCHEMATA;
> +--------------+-------------+--------------+
> | CATALOG_NAME | SCHEMA_NAME | SCHEMA_OWNER |

> | DRILL        | hivestg     | <owner>      |
