spark:expression ‘xxx’ is neither present in the group by

同一段SQL,在MYSQL中测试通过,挪到大数据执行报错:

org.apache.spark.sql.AnalysisException:
expression 'xxx' is neither present in the group by, nor is it an aggregate function.

Add to group by or wrap in first(or first_value)...

大数据查询遇到这个错误,解决方法已经提示。就是在xxx外面包裹first()函数。

至于原因:
