| Executing as background process |
| ********************************* |
| |
| |
| If you execute tsql as a background process, tsql will exit before executing a query because of some limitation of Jline2. |
| |
| Example: |
| |
| .. code-block:: sql |
| |
| $ bin/tsql -f aggregation.sql & |
| [1] 19303 |
| $ |
| [1]+ Stopped ./bin/tsql -f aggregation.sql |
| |
| |
| To avoid above problem, Tajo provides the -B command as follows: |
| |
| .. code-block:: sql |
| |
| $ bin/tsql -B -f aggregation.sql & |
