> If you have a partition with bucket/sort metadata set, then you alter the table to have
different bucket/sort metadata, and insert overwrite the partition with hive.enforce.bucketing=true
and/or hive.enforce.sorting=true, the partition data will be bucketed/sorted by the table's
metadata, but the partition will have the same metadata.
> This could result in wrong results.
