[jira] [Created] (DRILL-6013) requesting INFORMATION_SCHEMA with a
postgresql connector generates a null pointer exception
Gaëtan Lehmann created DRILL-6013:
-------------------------------------
Summary: requesting INFORMATION_SCHEMA with a postgresql connector generates a null pointer exception
Key: DRILL-6013
URL: https://issues.apache.org/jira/browse/DRILL-6013
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.11.0
Environment: debian 8, postgresql 8.6
Reporter: Gaëtan Lehmann
This select from https://drill.apache.org/docs/querying-the-information-schema/ works great with other sources (cp, dfs), but generates an error with postgresql:
{code:sql}
SELECT TABLE_SCHEMA, TABLE_NAME, TABLE_TYPE
FROM INFORMATION_SCHEMA.`TABLES`
ORDER BY TABLE_NAME DESC;
{code}
The error is:
{code}
Query Failed: An Error Occurred
org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR: NullPointerException: Error. Type information for table pg.information_schema._pg_foreign_data_wrappers provided is null. Fragment 0:0 [Error Id: c6f8bac2-f74f-4018-bbea-86ded61a432f on worker1:31010]
{code}
I got this error message in drillbit.log:
