> Doc the change wrought by the parent issue. Get it up into the refguide as 
> part of the difference between old hbases and hbase2.
> The change confused me and took me a while to untangle.
> The read count is for reads that return a non-empty result now. In old 
> hbase1, we'd increment the read-count even if an empty result. This makes 
> reads look bad in YCSB runs when compared to hbase1 (see how 
> totalRequestCount in hbase2 can be way above the sum of reads+writes; it is 
> because it increments even if the row is not found).
> Let me get this into refguide otherwise poor old operators will be baffled. 
> The release note on the parent is great; it just needs to be in our guide.
