Xiaoyu Yao commented on HDFS-9843: ---------------------------------- Thank you, [~cnauroth] for reviewing and committing the patch! > 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 > Fix For: 2.8.0 > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
