> This is a usability ticket, since it is possible to end up creating
> materialized views and realize that they need an additional flag to be picked
> up by the optimizer to do rewrites to.
> {code:sql}
> create materialized view ca as select * from customer, customer_address where
> c_current_addr_sk = ca_address_sk;
> set hive.materializedview.rewriting=true;
> select count(1) from customer, customer_address where c_current_addr_sk =
> ca_address_sk; -- does not use materialized view
> {code}
> Needs another step
> {code:sql}
> alter materialized view ca enable rewrite;
> {code}
> And then, it kicks in
> {code:sql}
> select count(1) from customer, customer_address where c_current_addr_sk =
> ca_address_sk;
> OK
