> In the getSplits() function of TableInputFormatBase, there is a line to compare the region's stop key and the given scan's stop key.
> If the region's stop key is smaller, then use the region's stop key instead of the one given by user.
> But the last region will not have a stop key, so comparing a null key to the given stop key  is always smaller, and the user's stop key is simply ignored.
