Install SQL Server 2019 big data tools

Applies to: SQL Server 2019 (15.x)


The Microsoft SQL Server 2019 Big Data Clusters add-on will be retired. Support for SQL Server 2019 Big Data Clusters will end on February 28, 2025. All existing users of SQL Server 2019 with Software Assurance will be fully supported on the platform and the software will continue to be maintained through SQL Server cumulative updates until that time. For more information, see the announcement blog post and Big data options on the Microsoft SQL Server platform.

This article describes the client tools that should be installed for creating, managing, and using SQL Server 2019 Big Data Clusters. The following section provides a list of tools and links to installation instructions. Before deploying a big data cluster, configure the tools marked required on Windows or Linux.

Big data cluster tools

The following table lists common big data cluster tools and how to install them:

Tool Required Description Installation
python Yes Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Many parts of big data clusters for SQL Server use python. Install python
Azure Data CLI (azdata) Yes Command-line tool for installing and managing a big data cluster. Install
kubectl1 Yes Command-line tool for monitoring the underlying Kubernetes cluster (More info). Windows | Linux
Azure Data Studio Yes Cross-platform graphical tool for querying SQL Server. Install
Data Virtualization extension Yes Extension for Azure Data Studio that provides a Data Virtualization wizard. Install
Azure CLI2 For AKS Modern command-line interface for managing Azure services. Used with AKS big data cluster deployments (More info). Install
mssql-cli Optional Modern command-line interface for querying SQL Server (More info). Windows | Linux
sqlcmd For some scripts Legacy command-line tool for querying SQL Server (More info). You might need to install the Microsoft ODBC Driver 11 for SQL Server before installing the SQLCMD package. Windows | Linux
curl 3 For some scripts Command-line tool for transferring data with URLs. Windows | Linux: install curl package
oc Required for Red Hat OpenShift and Azure Red Hat OpenShift deployments. oc is the Open Shift command line interface (CLI). Installing the CLI

1 You must use kubectl version 1.13 or later. Also, the version of kubectl should be plus or minus one minor version of your Kubernetes cluster. If you want to install a specific version on kubectl client, see Install kubectl binary via curl (on Windows 10 and Windows 11, use cmd.exe and not Windows PowerShell to run curl).


To use kubectl with a previously deployed cluster on Azure Kubernetes Service (AKS), you must set the cluster context with the following Azure CLI command:

az aks get-credentials --name <aks_cluster_name> --resource-group <azure_resource_group_name>

2 You must be using Azure CLI version 2.0.4 or later. Run az --version to find the version if needed.

3 If you are running on Windows 10 or Windows 11, curl is already in your PATH when running from a cmd prompt. For other versions of Windows, download curl using the link and place it in your PATH.

Which tools are required?

The previous table provides all of the common tools that are used with big data clusters. Which tools are required depends on your scenario. But in general, the following tools are most important for managing, connecting to, and querying the cluster:

  • Azure Data CLI (azdata)
  • kubectl
  • Azure Data Studio
  • Data Virtualization extension

The remaining tools are only required in certain scenarios. Azure CLI can be used to manage Azure services associated with AKS deployments. mssql-cli is an optional but useful tool that allows you to connect to the SQL Server master instance in the cluster and run queries from the command line. And sqlcmd and curl are required if you plan to install sample data with the GitHub script.

Install python offline

  1. On a machine with internet access, download one of the following compressed files containing Python:

    Operating system Download
  2. Copy the compressed file to the target machine and extract it to a folder of your choice.

  3. For Windows only, run installLocalPythonPackages.bat from that folder and pass the full path to the same folder as a parameter.

    installLocalPythonPackages.bat "C:\python-3.6.6-win-x64-0.0.1-offline\0.0.1"

Download and install Azure Data Studio

Azure Data Studio provides capabilities and features specifically for SQL Server Big Data Clusters.

Get the latest Azure Data Studio.

For details about the latest release, see the release notes.

Next steps

After configuring the tools, deploy a SQL Server 2019 big data cluster to Kubernetes in the Cloud or on-premises. For more information, see the following deployment articles:
