--------------------------------
Summary: 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
Reporter: Xiaoyu Yao
Assignee: Xiaoyu Yao
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.
