# Add the step ID to the configuration file

The configuration file, `org.pentaho.pdi.engine.spark.cfg`, contains the **forceCoalesceSteps** property. The property is a pipe-delimited listing of all the IDs for the steps that should run with a coalesced dataset. Pentaho supplies a default set to which you can add IDs for steps that generate errors.

Perform the following steps to add another step ID to the configuration file:

1. Navigate to the `data-integration/system/karaf/etc` folder and open the `org.pentaho.pdi.engine.spark.cfg` file.
2. Append your step ID to the **forceCoalesceSteps** property value list, using a pipe character separator between the step IDs.
3. Save and close the file.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/install/9.3-install/use-hadoop-with-pentaho/big-data-issues/spark-issues/steps-cannot-run-in-parallel/add-the-step-id-to-the-configuration-file.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
