【1】 Expected only partition pruning predicates
解决方案：设置spark.sql.hive.metastorePartitionPruning=false
【2】 Error in query: Detected cartesian product for INNER join between logical plans
Project-Join condition is missing or trivial.
Use the CROSS JOIN syntax to allow cartesian products between these relations
解决方案：设置spark.sql.crossJoin.enabled=true
可以在scala代码中添加 sqlC.sql("set spark.sql.crossJoin.enabled=true")
可以在Spark句群中配置；
