Xiao Chen updated HDFS-10899:
-----------------------------
Attachment: HDFS-10899.09.patch
patch 9:
- added a throttler. Note this won't be very accurate as we do not want
frequent lock/unlock, and the throttling has to happen out of locks after a
batch is created. Better approaches welcome. (Wasn't sure if follow-on means
separate jira preferable. can split that out if so to keep the central patch
size sane.).
- Should have mentioned in patch 8: I think after refactor the code is more
readable, but seems we can't lock/unlock within each method. This is similar to
{{FSDirEncryptionZoneOp#getEncryptionKeyInfo}}
- Fixed precommit complains.
> Add functionality to re-encrypt EDEKs.

> 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.
