-------------------------------------

Well, this I think is HIVE-12505. So it would need to be fixed in the hive version which is shipped in Spark...

> Insert overwrite mode will drop old data in hive table if there's old data.
> But if data deleting fails, no exception will be thrown and the data folder will be like:
> hdfs://uxs_nbp/nba_score/dt=2018-08-15/seq_num=2/part-00000
> hdfs://uxs_nbp/nba_score/dt=2018-08-15/seq_num=2/part-000001534916642513.
> Two copies of data will be kept.
