Hive DELETE Query with join condition on transactional table fails with HiveException: Unexpected column vector type STRUCT

Hive delete query with join on transactional table fails with HiveException: Unexpected column vector type STRUCT.

Repro Queries:

CREATE TABLE tab_s(a int) STORED AS ORC TBLPROPERTIES ('orc.compress'='SNAPPY');
INSERT INTO tab_s values(1);
CREATE TABLE tab_t(a int) STORED AS ORC TBLPROPERTIES ('orc.compress'='SNAPPY','transactional'='true');
INSERT INTO tab_t select * from tab_s;
DELETE FROM tab_t  WHERE EXISTS (select tab_s.a from tab_s where tab_s.a=tab_t.a);

Workaround:

This issue is seen with vectorized execution enabled. If we disable the vectorization, the query will run smoothly.

Property value change:

hive.vectorized.execution.enabled=false in hive-site.xml
