Stamatis Zampetakis commented on HIVE-27021:
--------------------------------------------
[~ibenny] Assuming that we change the behavior for drop operations what should
happen if we delete successfully the filesystem directory of the table but then
fail to update the metadata?
> Drop table should not be success on purge enabled tables if underlying HDFS
> data delete fails

> User A has drop privs for a table, but does not have delete privs on table
> HDFS path & table purge is enabled. When User A fires drop table command, HMS
> metadata is removed but HDFS files are left as-is & drop is reported
> successful leaving stale files.
> For example, the drop table query is completed successfully.
