Subject [jira] [Updated] (HADOOP-14705) Add batched reencryptEncryptedKey interface to KMS
Date Tue, 08 Aug 2017 03:26:01 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-14705.03.patch

Patch 3 to address all other comments from [~shahrs87].
Also moved more static functions to {{KMSUtil}}, and added checks for nullity on the params
- I think it makes sense to do the additional check now that it's moved to util. Existing
behaviors of these methods are not changed.

>                 URL: https://issues.apache.org/jira/browse/HADOOP-14705
>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: kms
>            Reporter: Xiao Chen
>            Assignee: Xiao Chen
>         Attachments: HADOOP-14705.01.patch, HADOOP-14705.02.patch, HADOOP-14705.03.patch
> 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.
