The Settings section of the Run configuration dialog box contains the following options when Spark is selected as the Engine for running a transformation:
| Option | Description |
|---|---|
| Protocol | Select whether the protocol of the Spark host URL uses standard HTTP or HTTPS (SSL encryption). |
| Spark host URL | Specify the address and port for the AEL daemon. |
Ask your Pentaho or IT administrator as to which Protocol to use and the value for Spark host URL. You can use Kettle parameters, variables, and kettle.properties for these options to create a run configuration that works across multiple environments. Your administrator must set up the Adaptive Execution Layer (AEL before you can use the Spark engine.
See the Administer Pentaho Data Integration and Analytics document if issues occur while trying to use the Spark engine.
