> It turns out that currently System.Catalog is not prevented from splitting generally, but does not allow splitting within a schema.
> In the multi-tenant case that is not good enough. When System.Catalog splits and a base table and view end up in different regions the following can happen:
> * DROP CASCADE no longer works for those views
> * Adding/removing columns to/from the base table no longer works
> Until PHOENIX-3534 is done we should simply prevent System.Catalog from splitting. (just like HBase:meta)
