             Summary: Mention spark.sql.crossJoin.enabled in implicit cartesian product error
msg
                 Key: SPARK-24128
                 URL: https://issues.apache.org/jira/browse/SPARK-24128
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.4.0
            Reporter: Henry Robinson


The error message given when a query contains an implicit cartesian product suggests rewriting
the query using {{CROSS JOIN}}, but not disabling the check using {{spark.sql.crossJoin.enabled=true}}. It's
sometimes easier to change a config variable than edit a query, so it would be helpful to
make the user aware of their options.
