Namit Jain commented on HIVE-3646:
----------------------------------
>From the code, it looks like, it doesn't matter if the tables/partitions are
>hdfs or non-hdfs.
They will be dropped either way.

Can you document the behavior above ?
> Add 'IGNORE PROTECTION' predicate for dropping partitions

> There are cases where it is desirable to move partitions between clusters.
> Having to undo protection and then re-protect tables in order to delete
> partitions from a source are multi-step and can leave us in a failed open
> state where partition and table metadata is dirty. By implementing an 'rm
> -rf'-like functionality, we can perform these operations atomically.
