2) Sometimes I find that managed tables are not removed from HDFS even after I drop them from the Hive shell. After a "drop table foo", foo does not show up in a "show tables" listing however that table is present in HDFS. These are not external tables.

For example based on the UserGroupAll + StickyBit a user might be able to create a table but another user might not be able to drop them. I had one weird issue where I could not drop a table as a different user because one of the subdirs had a sticky bit and attempting to move the sticky bit caused a failed file operation On Fri, Dec 4, 2015 at 10:33 AM, Timothy Garza < timothy.ga...@collinsongroup.com> wrote: > No, definitely not.
