> 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.default | <owner> |
> | DRILL | hivestg | <owner> |
> | DRILL | dfs.default | <owner> |
> | DRILL | dfs | <owner> |
> | DRILL | cp.default | <owner> |
> | DRILL | cp | <owner> |
> | DRILL | INFORMATION_SCHEMA | <owner> |
> +--------------+-------------+--------------+
> 7 rows selected (0.131 seconds)
> Given tables inside hivestg.default as follows:
> 0: jdbc:drill:schema=hivestg> select * from INFORMATION_SCHEMA.`TABLES`;
> +---------------+--------------+------------+------------+
> | TABLE_CATALOG | TABLE_SCHEMA | TABLE_NAME | TABLE_TYPE |
> +---------------+--------------+------------+------------+
> | DRILL | hivestg.default | sneaky | TABLE |
> | DRILL | hivestg.default | bit_table | TABLE |
> | DRILL | hivestg.default | stinyint_table | TABLE |
> | DRILL | hivestg.default | no_null_integer_table | TABLE |
> | DRILL | hivestg.default | real_table | TABLE |
> | DRILL | hivestg.default | integer_table | TABLE |
> A generated query would look as follows:
> SELECT * FROM `hivestg.default`.`integer_table`
> This fails to execute with the following error:
> 0: jdbc:drill:schema=hivestg> SELECT * FROM `hivestg.default`.`integer_table`;
> Query failed: org.apache.drill.exec.rpc.RpcException: Remote failure while
