Nicolas Spiegelberg commented on HBASE-1183:
--------------------------------------------
@jgray: I saw your comment on the prepend on this JIRA @ 03/Feb/09. I was
looking at the split code to analyze binary split versus hex-string split for
the RegionSplitter code. I thought the {1,0} looked unnecessary since you
prepend it to A & B then issue C=A-B. I just wanted to get clarification in
case this is ever refactored, low priority.
> New MR splitting algorithm and other new features need a way to split a key

> For HBASE-1172 and other functionality coming soon, we need to be able to
> take a [start,stop) range and divide it into chunks.
> For example, we have 10 regions but want to run 30 maps. We need to divide
> each region into three key ranges for the start/stop of each scanner.
> Implementing using java.math.BigInteger
> Will also include a couple additional helpers in Bytes to make life easy.
