**Apache Airflow version**:

2.1.0

**Environment**:

- self hosted docker-compose based stack

**What happened**:

Using JDBCOperator if the sql result in an error we got only 
```
[2021-06-21 11:05:55,377] {local_task_job.py:151} INFO - Task exited with return code 1
```

Before upgrading from 2.0.1 we got error details in logs:
```
jaydebeapi.DatabaseError: java.sql.SQLException:... [MapR][DrillJDBCDriver](500165) Query execution error. Details: VALIDATION ERROR:...
``` 

**What you expected to happen**:

See `SQLException` in logs

**How to reproduce it**:

Perform a generic SQL task with broken SQL.

**Anything else we need to know**:

I think is somehow related to https://github.com/apache/airflow/commit/abcd48731303d9e141bdc94acc2db46d73ccbe12#diff-4fd3febb74d94b2953bf5e9b4a981b617949195f83d96f4a589c3078085959b7R202
