> create table t1(a int, b varchar(128), c float) stored as orc TBLPROPERTIES
> ('transactional'='true');
> insert into t1(a,b, c) values (1, 'one', 1.1), (2, 'two', 2.2), (NULL, NULL,
> NULL);
> create materialized view mat1 stored as orc TBLPROPERTIES
> ('transactional'='true') as
> select a,b,c from t1 where a > 0 or a is null;
> delete from t1 where a = 1;
> alter table t1 compact 'major';
> -- Wait until compaction finished.
> alter materialized view mat1 rebuild;
> {code}
> Expected result of query
> {code}
> select * from mat1;
> {code}
> {code}
> 2 two 2
> NULL NULL NULL
> {code}
> but if incremental rebuild is enabled the result is
> {code}
> 1 one 1
> 2 two 2
> NULL NULL NULL
> {code}
> Cause: Incremental rebuild queries whether the source tables of a
> materialized view has delete or update transaction since the last rebuild
> from metastore from COMPLETED_TXN_COMPONENTS table. However when a major
> compaction is performed on the source tables the records related to these
> tables are deleted from COMPLETED_TXN_COMPONENTS.
