Chris Nauroth commented on HDFS-9843:
-------------------------------------
I think this patch missed out on a pre-commit run due to some Jenkins
infrastructure problems yesterday. I just resubmitted a pre-commit run
manually.
> Document distcp options required for copying between encrypted locations

> Key: HDFS-9843
> URL: https://issues.apache.org/jira/browse/HDFS-9843
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: distcp, documentation, encryption
> Affects Versions: 2.6.0
> Reporter: Xiaoyu Yao
> Assignee: Xiaoyu Yao
> Attachments: HDFS-9843.00.patch, HDFS-9843.01.patch,
> HDFS-9843.02.patch
>
>
> In TransparentEncryption.md#Distcp_considerations document section, we have
> "Copying_between_encrypted_and_unencrypted_locations" which requires
> -skipcrccheck and -update.
> These options should be documented as required for "Copying between encrypted
> locations" use cases as well because this involves decrypting source file and
> encrypting destination file with a different EDEK, resulting in different
> checksum at the destination. Distcp will fail at crc check if -skipcrccheck
> if not specified.
> This ticket is opened to document the required options for "Copying between
> encrypted locations" use cases when using distcp with HDFS encryption.
