Incremental rebuild of non-transaction materialized view fails

create table t1 (a int, b int) stored as orc TBLPROPERTIES ('transactional'='true');

insert into t1 values (1,1), (2,1), (3,3);

create materialized view mv1 as
select a, b from t1 where b = 1;

delete from t1 where a = 2;

explain
alter materialized view mv1 rebuild;

org.apache.hadoop.hive.ql.parse.SemanticException: Attempt to do update or delete on table mv1 that is not transactional
