spark作表链接的时候出现这个错误，sql

Exception in thread "main" org.apache.spark.sql.AnalysisException: Detected cartesian product for LEFT OUTER join between logical plans LocalLimit 21apache

出现错误，这时，须要添加spa

spark.conf.set("spark.sql.crossJoin.enabled", "true")code

再次运行，能够成功。it

由于，2.x中默认不支持笛卡尔积操做，须要经过参数spark.sql.crossJoin.enabled开启spark
