Wei-Chiu Chuang commented on HDFS-12359:
----------------------------------------

Hi [~xiaochen] thanks again for the patch.

Would you please add a test to demonstrate:
bq. We should fix re-encryption to not require additional ACLs than original encryption.

I would expect you have a test where it fails if the patch is reverted.

> This was caught from KMS acl testing.
> HDFS-10899 gets the current key versions from KMS directly, which requires {{READ}} acls.
> It also calls invalidateCache, which requires {{MANAGEMENT}} acls.
> We should fix re-encryption to not require additional ACLs than original encryption.
