Xiao Chen updated HADOOP-14705:
-------------------------------
Attachment: HADOOP-14705.01.patch
Patch 1 to express the idea and for high-level review.
Will add more test cases, and look to see if some of the util methods can be
de-dup'ed.
> Add batched reencryptEncryptedKey interface to KMS

> Key: HADOOP-14705
> URL: https://issues.apache.org/jira/browse/HADOOP-14705
> Project: Hadoop Common
> Issue Type: Improvement
> Components: kms

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