> Admin#isTableAvailable checks if it can getServerName for the meta entries it
> reads. During the time of split server location are added to the meta entries
> in MetaTableAccessor#splitRegion although the description of the method says
> "Does not add the location information to the daughter regions since they are
> not open yet.". At this point during the split daughter regions are not
> actually open, so we can get to a state where parent is offline, daughters
> are not yet open but isTableAvailable returns true.
