> ALTER TABLE RENAME fails if the original table directory is in a different HDFS encryption zone than the parent directory, i.e. the Hive warehouse dir. (Note RENAME only applies to managed tables.)
> This is somewhat of a corner case because it requires that a managed table be created in Impala/Hive and, before any data is inserted, it be added as an HDFS encryption zone (because encryption zones must be configured on empty directories). This does not apply to external tables which use ALTER TABLE ... SET LOCATION.
