Date Tue, 01 Aug 2017 04:20:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-14705?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

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.

> 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.
