Xiao Chen commented on HDFS-10899:
----------------------------------

Thanks Suraj for the discussions offline. Some high-level conclusion was that re-encrypt being a EEK op, is better controlled under EEK op, so sticking with generate_eek for now. Will post a WIP patch momentarily.

> Currently when an encryption zone (EZ) key is rotated, it only takes effect on new EDEKs. We should provide a way to re-encrypt EDEKs after the EZ key rotation, for improved security.
