Hi, Just noticed that http://spark.apache.org/docs/latest/sql-migration-guide-upgrade.html (Spark 2.4.5) has formatting issues in "Upgrading from Spark SQL 2.4.3 to 2.4.4" [1] which got fixed in master [2]. That's OK.
What made me wonder was the other change to the section "Upgrading from Spark SQL 2.4 to 2.4.5" [3] that had the following item included: "Starting from 2.4.5, SQL configurations are effective also when a Dataset is converted to an RDD and its plan is executed due to action on the derived RDD. The previous behavior can be restored setting spark.sql.legacy.rdd.applyConf to false: in this case, SQL configurations are ignored for operations performed on a RDD derived from a Dataset." Why was this removed in master [4]? It was mentioned in "Notable changes" of Spark Release 2.4.5 [5].
