> Drop table/index/database can result in orphaned locations

> Key: HIVE-3134
> URL: https://issues.apache.org/jira/browse/HIVE-3134
> Project: Hive
> Issue Type: Bug

> Reporter: Kevin Wilfong

>
> Today when a managed table has a partition with a location which is not a
> subdirectory of the table's location, when the table is dropped the
> partition's data is not deleted from HDFS, resulting in an orphaned directory
> (the data exists but nothing points to it).
> The same applies to dropping a database with cascade and a table has a
> location outside the database.
> I think it is safe to assume managed tables/partitions own the directories
> they point to, so we should clean these up.
