Quickstart: Create Apache Spark cluster in Azure HDInsight using Azure portal

In this quickstart, you use the Azure portal to create an Apache Spark cluster in Azure HDInsight. You then create a Jupyter notebook, and use it to run Spark SQL queries against Apache Hive tables. Azure HDInsight is a managed, full-spectrum, open-source analytics service for enterprises. The Apache Spark framework for HDInsight enables fast data analytics and cluster computing using in-memory processing. Jupyter notebook lets you interact with your data, combine code with markdown text, and do simple visualizations.

Create an Apache Spark cluster in HDInsight

You use the Azure portal to create an HDInsight cluster that uses Azure Storage Blobs as the cluster storage. For more information on using Data Lake Storage Gen2, see Quickstart: Set up clusters in HDInsight.


Billing for HDInsight clusters is prorated per minute, whether you are using them or not. Be sure to delete your cluster after you have finished using it. For more information, see the Clean up resources section of this article.

  1. In the Azure portal, select Create a resource.

    Azure portal create a resource

  2. On the New page, select Analytics > HDInsight.

    Azure portal create HDInsight

  3. Under Basics, provide the following values:

    Property Description
    Subscription From the drop-down, select an Azure subscription used for this cluster. The subscription used for this quickstart is Azure.
    Resource group Specify whether you want to create a new resource group or use an existing one. A resource group is a container that holds related resources for an Azure solution. The resource group name used for this quickstart is myResourceGroup.
    Cluster name Give a name to your HDInsight cluster. The cluster name used for this quickstart is myspark2019.
    Location Select a location for the resource group. The template uses this location for creating the cluster as well as for the default cluster storage. The location used for this quickstart is East US.
    Cluster type Select Spark as the cluster type.
    Cluster version This field will auto-populate with the default version once the cluster type has been selected.
    Cluster login username Enter the cluster login username. The default name is admin. You use this account to login in to the Jupyter notebook later in the quickstart.
    Cluster login password Enter the cluster login password.
    Secure Shell (SSH) username Enter the SSH username. The SSH username used for this quickstart is sshuser. By default, this account shares the same password as the Cluster Login username account.

    Select Next: Storage >> to continue to the Storage page.

  4. Under Storage, provide the following values:

    Property Description
    Primary storage type Use the default value Azure Storage.
    Selection method Use the default value Select from list.
    Primary storage account Use the auto-populated value.
    Container Use the auto-populated value.

    Select Review + create to continue.

  5. Under Review + create, select Create. It takes about 20 minutes to create the cluster. The cluster must be created before you can proceed to the next session.

If you run into an issue with creating HDInsight clusters, it could be that you don't have the right permissions to do so. For more information, see Access control requirements.

Create a Jupyter notebook

Jupyter Notebook is an interactive notebook environment that supports various programming languages. The notebook allows you to interact with your data, combine code with markdown text and perform simple visualizations.

  1. Open the Azure portal.

  2. Select HDInsight clusters, and then select the cluster you created.

    open HDInsight cluster in the Azure portal

  3. From the portal, select Cluster dashboards, and then select Jupyter Notebook. If prompted, enter the cluster login credentials for the cluster.

  4. Select New > PySpark to create a notebook.

    A new notebook is created and opened with the name Untitled(Untitled.pynb).

Run Apache Spark SQL statements

SQL (Structured Query Language) is the most common and widely used language for querying and defining data. Spark SQL functions as an extension to Apache Spark for processing structured data, using the familiar SQL syntax.

  1. Verify the kernel is ready. The kernel is ready when you see a hollow circle next to the kernel name in the notebook. Solid circle denotes that the kernel is busy.

    When you start the notebook for the first time, the kernel performs some tasks in the background. Wait for the kernel to be ready.

  2. Paste the following code in an empty cell, and then press SHIFT + ENTER to run the code. The command lists the Hive tables on the cluster:


    When you use a Jupyter Notebook with your HDInsight cluster, you get a preset sqlContext that you can use to run Hive queries using Spark SQL. %%sql tells Jupyter Notebook to use the preset sqlContext to run the Hive query. The query retrieves the top 10 rows from a Hive table (hivesampletable) that comes with all HDInsight clusters by default. It takes about 30 seconds to get the results. The output looks like:

    Every time you run a query in Jupyter, your web browser window title shows a (Busy) status along with the notebook title. You also see a solid circle next to the PySpark text in the top-right corner.

  3. Run another query to see the data in hivesampletable.

    SELECT * FROM hivesampletable LIMIT 10

    The screen shall refresh to show the query output.

  4. From the File menu on the notebook, select Close and Halt. Shutting down the notebook releases the cluster resources.

Clean up resources

HDInsight saves your data in Azure Storage or Azure Data Lake Storage, so you can safely delete a cluster when it is not in use. You are also charged for an HDInsight cluster, even when it is not in use. Since the charges for the cluster are many times more than the charges for storage, it makes economic sense to delete clusters when they are not in use. If you plan to work on the tutorial listed in Next steps immediately, you might want to keep the cluster.

Switch back to the Azure portal, and select Delete.

Azure portal delete an HDInsight cluster

You can also select the resource group name to open the resource group page, and then select Delete resource group. By deleting the resource group, you delete both the HDInsight cluster, and the default storage account.
