> Recently we made several behavior changes to Spark SQL, to make it more ANSI SQL compliant or fix some unreasonable behaviors. For backward compatibility, we add configs to allow users fallback to the old behavior and plan to remove them in Spark 3.0. It's better to put these configs under spark.sql.legacy.*
