> In HDFSIntegrityFixer#mergeOverlaps(), there is a logic to create the final range of the region after the overlap.
> I can see one issue with this code
> {code}
>             if (RegionSplitCalculator.BYTES_COMPARATOR
>                     .compare(hi.getEndKey(), range.getSecond()) > 0) {
>               range.setSecond(hi.getEndKey());
>             }
> {code}
> Here suppose the regions include the end region for which the endKey will be empty, we need to get finally the range with endkey as empty byte[]
> But as per the above logic it will see that any other key greater than the empty byte[] and will set it.
> Finally the new region created will not get endkey as empty byte[]
