dfs.bytes-per-checksum was added as part of HADOOP-6419 /
00de6db0e3976cf0108010ecbd6e73a5ceab7b1f. It looks like the internal-to-Yahoo!
commit that was part of that one accidentally included a lot more than what was
documented. So if there is any ASF-level documentation of the change, it's
going to be in a JIRA patch somewhere, likely in the 0.20 timeline.
