Lars Hofhansl commented on PHOENIX-4360:
----------------------------------------
We can have test, but it we'd just test that HBase doesn't split when told not
to split. (and we have tests for that in HBase).
[~apurtell], good point. Could just use {{DisabledRegionSplitPolicy}}
> 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)
