While some filesystems (e.g. HDFS) may checksum data, not all do. Data files may also accumulate errors when copied between filesystems. For back-compatibility, we cannot easily add checksums to existing data files, but a new codec provides us with the opportunity to do this. -- This message is automatically generated by JIRA.
