> in case of vectorization, the summary row object was left as is (presumed
> null earlier); which may cause it to be inconsistent isNull conditions in
> .VectorHashKeyWrapperBatch
> issue happens only if:
> * vectorizable groupby
> * groupping set contains empty
> * non-trivial empty; mapper is run
> * groupping key is select ; with a type which is backed by a bytea; ex:string
> {code}
> set hive.vectorized.execution.enabled=true;
> create table tx2 (a integer,b integer,c integer,d double,u string,bi binary)
> stored as orc;
> insert into tx2 values
> (1,2,3,1.1,'x','b'),
> (3,2,3,1.1,'y','b');
> select sum(a),
> u,
> bi,
> 'asd',
> grouping(bi),
> 'NULL,1' as expected
