      Description

      After the improved CRC32C checksum feature became default, some of use cases involving data movement are no longer supported. For example, when running DistCp to copy from a file stored with the CRC32 checksum to a new cluster with the CRC32C set to default checksum, the final data integrity check fails because of mismatch in checksums.
