> 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.
