Todd Lipcon commented on HDFS-3689:
-----------------------------------
Hey Suresh. This is an interesting idea which I've thought about a couple
times, too.
Whenever I think about it, though, I wonder: will the variable length blocks
have to all be multiples of the checksum chunk size? Or do you think they can
start and stop on arbitrary byte boundaries?
