[jira] [Created] (HIVE-18280) Hive Support for SMB join to ignore hidden files

Jesus Camacho Rodriguez created HIVE-18280:
----------------------------------------------

             Summary: Hive Support for SMB join to ignore hidden files
                 Key: HIVE-18280
                 URL: https://issues.apache.org/jira/browse/HIVE-18280
             Project: Hive
          Issue Type: Bug
          Components: Operators
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


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
