Xiao Chen commented on HADOOP-14705:
------------------------------------
bq. It is based on HADOOP-14779, and optimizes reencryptEncryptedKeys to use
the same codec (and en/de-cryptor), and only getCurrentKey once from the key
name.
Thanks for looking. As
[noted|https://issues.apache.org/jira/browse/HADOOP-14705?focusedCommentId=16129130&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16129130],
could you please apply HADOOP-14779, then patch 5 here? Only reason to
separate out HADOOP-14779 is for cleanness.

> HADOOP-13827 already enabled the KMS to re-encrypt a {{EncryptedKeyVersion}}.
> As the performance results of HDFS-10899 turns out, communication overhead
> with the KMS occupies the majority of the time. So this jira proposes to add
> a batched interface to re-encrypt multiple EDEKs in 1 call.
