# Install a new instance of the Spark client

If you do not have a supported Spark client installed, you need to install your own instance. Perform the following steps:

1. Download the Spark client from the following location to the machine where you will run the AEL daemon: <http://spark.apache.org/downloads.html>

   As a best practice, use Apache Spark client 2.3 or 2.4. Version 2.3 is used in the following examples.

   For example, download `spark-2.3.0-bin-hadoop2.7.tgz` if you are using Spark 2.3 on Hadoop 2.7
2. Extract the downloaded TGZ file to a designated folder where the Spark client will reside.

   For AEL installation, the folder name you designate is the target folder for the **sparkHome=** parameter.

   For example, this extraction command: `tar zxf /your_path/spark-2.3.0-bin-hadoop2.7.tgz` results in the following path:

   `/your_path/spark-2.3.0-bin-hadoop2.7/`

   where: `/your_path` is the designated folder.
3. Copy the path that was created to the `application.properties` file and the**sparkHome=** parameter as shown below.

   `sparkHome=/your_path/spark-x.x.x-bin-hadoopx.x/`

   where:

   `your_path:` is the folder where you downloaded or unzipped the TGZ file.

   `spark-x.x.x-bin-hadooop.x:` is the version of the Spark client you are using.

   For example, if your folder is called `spark230`:

   `sparkHome=/spark230/spark-2.3.0-bin-hadoop2.7/`

## 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/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/set-up-the-adaptive-execution-layer-ael/before-you-begin/spark-client-cp/spark-client-install-new-instance.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.
