Table of Contents:
1. Prerequisites on Azure portal
The entry point to Azure Databricks is https://portal.azure.com. From the home page navigate to the Databricks section.
Click
Your account must have Owner or Contributor privileges on Databrick's workspace to be able to access it.
By default, the Azure Databricks cluster is not running. Either create a new cluster or start the existing one (be sure to change the cluster filter to show all clusters).
In Advanced Options set up Spark config for a connection to ADLS Gen2 storage. The configuration is a set of a key:value pairs separated by single spaces. OAuth parameter values are the same as credentials used in ADLS.

Write down the server hostname, port, and JDBC URL which will be used in the SM storage definition.
To create a database, create a Notebook
for the submission of SQL queries first.
Now you can run create database SQL query.
Create TOKEN for remote access in User Settings (top right corner icon).
Save token for later use in SAP configuration.

3. Create ADLS Gen 2 storage
ADLS storage is required as storage for temporary data. Please follow this guide to create the storage (SM-2211) Azure Data Lake Gen2.
4. Download Spark JDBC drivers
Download Spark JDBC driver from https://databricks.com/spark/odbc-driver-download
Upload the .jar file to SAP application server at /sapmnt/<SID>/global/security/dvd_conn/spark/
The file needs to be owned by <sid>adm:sapsys
5. Create Databricks storage
Go to transaction /DVD/SM_SETUP
Create new storage of type SM_TRS_MS
This storage use storage of type SM_TRS_MS
, where more information about setup can be find (SM-2211) Hadoop Storage Setup.
