Kihwal Lee commented on HADOOP-8060:
------------------------------------
> so the changes are contained in common
Maybe this is confusing. The changes pertaining to the addition of checksum
types to CreateFlag does not necessitate new dependencies that are external to
Common. I.e. can be done in a separate jira and won't break anything alone.
> Add a capability to use of consistent checksums for append and copy

> 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.
