             Summary: NPE when generating incremental rebuild plan of 
materialized view with empty Iceberg source table
                 Key: HIVE-27307
                 URL: https://issues.apache.org/jira/browse/HIVE-27307
             Project: Hive
          Issue Type: Bug
            Reporter: Krisztian Kasa


{code}
set hive.support.concurrency=true;
set hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;

create external table tbl_ice(a int, b string, c int) stored by iceberg stored 
as orc tblproperties ('format-version'='1');
create external table tbl_ice_v2(d int, e string, f int) stored by iceberg 
stored as orc tblproperties ('format-version'='2');

insert into tbl_ice_v2 values (1, 'one v2', 50), (4, 'four v2', 53), (5, 'five 
v2', 54);

create materialized view mat1 as
select tbl_ice.b, tbl_ice.c, tbl_ice_v2.e from tbl_ice join tbl_ice_v2 on 
tbl_ice.a=tbl_ice_v2.d where tbl_ice.c > 52;

-- insert some new values to one of the source tables
insert into tbl_ice values (1, 'one', 50), (2, 'two', 51), (3, 'three', 52), 
(4, 'four', 53), (5, 'five', 54);

alter materialized view mat1 rebuild;
