Scoreboard kind of functionality

If I have a bunch of MRs and I want to keep a tab on what they should
process in terms of scope of row ids
eg,
first run :

startRow1
stopRowN

second run
startRowN+1
stopRowM

and similar for others,
is there any light weight accomplish this?

thanks,
vk

So you are configuring your Scan to scan only the specified start/stop
rows? I guess you could store that anywhere right? Like HBase?
