Yes, in Falcon's data retention (FALCON-870
<https://issues.apache.org/jira/browse/FALCON-870>)

That's been backported as a hot-fix for those who need to enforce Calendar
based retention policies from an admin interface.

For example - with that patch, Falcon can be set up to delete files which
have mtime older than 1 month and atime older than 1 week.

On the other hand, these dirs are supposed to be cleaned up via
FileSystem.deleteOnExit().

How long has your HiveServer2 been up & does restarting it delete these?

If that works - are you using Hue as your query interface? (Hue does not
use standard sessions).

 
Cheers,
