org.apache.spark.sql.catalyst.analysis.UnresolvedException: Invalid call to toAttribute on unresolve

执行形如下列的spark sql：

select xxx from TABLENAME WHERE x=1 having CONDITION = 1

报错：

原因：
https://spark.apache.org/docs/2.4.0/sql-migration-guide-upgrade.html#upgrading-from-spark-sql-23-to-24

spark sql在2.3和2.4的处理逻辑不一样，
在2.3中如果没有GROUP BY，则HAVING会当成WHERE进行处理
但2.4中就会报上述错误。

可参考的解决方案：
1.改sql语句，加上group by
2. 启动的时候设置spark.sql.legacy.parser.havingWithoutGroupByAsWhere 为true ，即 ./bin/spark-sql --conf spark.sql.legacy.parser.havingWithoutGroupByAsWhere =true
