Since you are a data engineer I would start by learning Scala. The parts of Scala you would need to learn are pretty basic. Start with the examples on the Spark website, which gives examples in multiple languages. Think of Scala as a typed version of Python. You will find that the error messages tend to be much more meaningful in Scala because that is the native language of Spark. If you don’t want to to install the JVM and Scala, I highly recommend Databricks community edition as a place to start.

I am currently working as a data engineer and I am working on Power BI, SSIS (ETL Tool). For learning purpose, I have done the setup PySpark and also able to run queries through Spark on multi node cluster DB (I am using Vertica DB and later will move on HDFS or SQL Server).

I have good knowledge of Python also.
