Wrong comment format, will send it again.
bq. We will read cells from MOB files only on demand right. First we read from ref cf files
and there any way the readPoint check is there. Only if it passes, we will call get cell on
MOB. Or the case is like with same key (rk,cf,q,ts,type) we have 2 cells and old cell in ref
cf got cleared by readPoint check but we read the new cell from MOB file?
Hi Anoop Anoop Sam John, I think we could directly use the readPt to directly seek the cell
in mob file. I have refined the patch based on the V1, and will upload it later.

violations.  We want to fix before calling merge to trunk.
