Review comment:
I think Phoenix already tested add/dropColumnOnParentTableView when
ALLOW_SPLITTABLE_SYSTEM_CATALOG_ROLLBACK=false so no dup tests are needed.
Just want to double confirm :)

> For pre-4.15 clients, we have to block adding/dropping a column to a table if
> it has child views since we can’t do any checkAndPut distributed locking (see
> [this|https://github.com/apache/phoenix/blob/6ecc66738e576a5349605c2f5b20003df03f95de/phoenix-core/src/main/java/org/apache/phoenix/coprocessor/MetaDataEndpointImpl.java#L2595-L2616]).
>
> However, this is only prevented if the parent is a table and not if the
> parent is a view. We should extend [the
> condition|https://github.com/apache/phoenix/blob/6ecc66738e576a5349605c2f5b20003df03f95de/phoenix-core/src/main/java/org/apache/phoenix/coprocessor/MetaDataEndpointImpl.java#L2591]
> to also cover views since conflicting mutations on its children can also
> lead to inconsistencies.
