      Support for multiple Spark contexts in the same driver has been removed in Spark 3.

      Description

      Multiple Spark contexts are discouraged and it has been warning from 4 years ago (see SPARK-4180).

      It could cause arbitrary and mysterious error cases. (Honestly, I didn't even know Spark allows it).
