I think you can easily learn to walk also with Spark. There are a lot of beginners Spark tutorial online. You can see, for instance, https://community.cloud.databricks.com https://community.cloud.databricks.com. They give you a Spark cluster where you can start and there are several tutorials in a notebook-style. Check it out. Of course, you could start your ETL / Data Engineering in a more "traditional" way trying to learn about relational databases and the likes. But I would suggest you to start directly with Spark. You can use it with lots of other big data tools (such as Hadoop/Hive and also S3) and you could also find some interesting Machine Learning use case.
