When doing an SMB join with ORC, we get the following error:
FAILED: SemanticException Error 10141: Bucketed table metadata is not correct. Fix the metadata or don't use bucketed mapjoin, by setting hive.enforce.bucketmapjoin to false. The number of buckets for table its_purchase_line_item_mio partition create_month=2003-04/etl_process_run_id=36766536 is 512, whereas the number of files is 513
The partition contained additional _mcinfo file, that caused the failure.
We would like Hive to ignore such hidden/special files
