"left join" complains and tells me I need to turn on "spark.sql.crossJoin.enabled=true".
But when I persist one dataframe, it runs fine. Why do you have to "persist"? org.apache.spark.sql.AnalysisException: Detected implicit cartesian product for INNER join between logical plans SELECT * FROM LHS left join RHS on LHS.R = RHS.R The above happens in both Spark 2.3.3 and 2.4.4.
