             Summary: Unable to run query containing quoted schema name
                 Key: DRILL-623
                 URL: https://issues.apache.org/jira/browse/DRILL-623
             Project: Apache Drill
          Issue Type: Bug
            Reporter: George Chow


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 running query.[error_id: "fe7731f0-c032-4049-9204-61bb7c7340cb"
