> hbase-480 adds a merge tool. Seems to work for two adjacent regions in tests
> but not for the case where we've made two overlapping regions: i.e. both have
> a start key of 'A' but one regions endkey is less than the end key of the
> others (See up on Lars cluster hbase-471). I ran the merge and it made a new
> region with the right start and end keys but there was nothing in it.
> We need this tool to do fix up when hbase goes awry.
