-------------------------------------
@ram
Sorry, I'm not clear about your mean.
In current logic, we will getting an IOException in logs and return null for
getSplitPoint.
Do you mean we directly return null for HFileBlockIndex#midkey() if (rootCount
== 0) rather than throws an IOException?
> Split point should not be equal with start row or end row
