----------------------------------------
Summary: Oracle JDBC configuration filters necessary Calcite
parameter
Key: DRILL-3970
URL: https://issues.apache.org/jira/browse/DRILL-3970
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.2.0
Environment: Mac OS X 10.10
Reporter: Kyle Marek-Spartz
After getting around DRILL-3958, I created a JDBC storage connection to an
Oracle database. However, when I execute queries, I get errors of this sort:
{code}
0: jdbc:drill:zk=local> show tables from oracle;
Error: SYSTEM ERROR: IllegalArgumentException: duplicate key: WWV_FLOW_DUAL100
Fragment 0:0
[Error Id: f34cc14b-42ea-4caf-a849-205eb5570ba2 on
kmarekspartz-mb.stp01.office.gdi:31010] (state=,code=0)
{code}
This seems similar to CALCITE-880, which was closed as a configuration issue,
suggesting adding {{"jdbcSchema": "ORACLE_SCHEMA_NAME"}} to the JSON
configuration. Adding this to the Drill storage configuration option gives a
{{Invalid JSON mapping}} error, which likely is due to a lack of {{jdbcSchema}}
in {{JdbcStorageConfig.java}}:
