> If a RS is slow to open a Region, the Master will give the Region to another
> to open it (In this case, was a massive set of edits to process and a load of
> StoreFiles to open...). Should the original RS succeed with its open
> eventually, on reporting the master the successful open, the Master currently
> kills the RS because the region is supposed to be elsewhere.
> This is an easy fix.
> The RS does not fully open a Region until Master gives it the go so just
> close the region if master rejects the open....
> See '6.1.1 If Master gives Region to another to Open, old RS will be kill
> itself on reject by Master; easy fix!' in
