Chris Nauroth commented on HDFS-9843:
-------------------------------------
Hello [~xyao]. The content looks good. I'm confused about the hyperlinks for
-skipcrccheck and -update though. These end up linking to
TransparentEncryption.html#a-skipcrccheck and
TransparentEncryption.html#a-update. There are no anchors in the page that
match those, so it effectively means the browser just redisplays the same page.
I also see there is an existing similar one for -px, which already exists
before your patch.
Do you know what is the intent of these hyperlinks? I checked the DistCp page
for matching anchors, thinking maybe the intent is to link to a different page,
but I didn't see the anchors over there either.

> 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
>
>
> 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.
