Xiao Chen commented on HDFS-10899:
----------------------------------
Thanks for the comments [~sacharya].
bq. It would be great if this was made as a REST API endpoint along with the
other key creation/management REST API.
Sure, this will be part of
http://hadoop.apache.org/docs/r3.0.0-alpha1/hadoop-kms/index.html#KMS_HTTP_REST_API
bq. May be we can add a new parameter to the key roll REST API saying something
along the lines of roll all the zones with given key
I have a mixed feeling of this. As listed in the Alternatives of 'HDFS
client-side', it is more admin-friendly. But it will also make the already
not-so-friendly ACLs more complex.
Also, in this example, to support the scenario where admin accidentally missed
a zone 'd', we still need the {{reencrypt}} command to re-encrypt it. So I'd
like to leave out rollover's option for now, and focus on re-encrypt in this
jira. Can choose to add the option, or maybe {{reencrypt -key}} as an
improvement later.
bq. Create an endpoint to check the status or reencryption.
Good idea, I was thinking maybe add this to NN webui. Will work on CLI checks
first and hook up an endpoint afterwards.

> 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.
