   @n3nash  The hive/hudi table have contain partition 'year=2020/month=01/day=11', when you write a new partition 'year=2020/month=11/day=01' to the table, it will throw error! Because in the getPartitionEvents method logic, 'year=2020/month=01/day=11' will transfer to be "01, 11, 2020" and 'year=2020/month=11/day=01' will transfer to be "01, 11, 2020" too, So the new partition 'year=2020/month=11/day=01' is treated as a update event actually it is a new partition, and the coming processing will update the table partitions using "ALTER TABLE XX PARTITION (year='2020',month='11',day='01') SET LOCATION ..."! To update a not existed partition will throw error!
