James Taylor commented on PHOENIX-4360:
---------------------------------------
I think your patch is fine, [~lhofhansl]. Since this is configured on the
SYSTEM.CATALOG table, best to leave it in place as we'll go back to the
previous version once the system catalog table is splittable (as the previous
version enforces that splits only occur between different tenant+schema
combinations.
> Prevent System.Catalog from splitting

> Just talked to [~jamestaylor].
> 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)
