Is there any benefit of keeping the number of buckets as two raised to the

Hi,
We stumbled on some weird behaviour of mapjoin in hive 3.1
Sample schema:
> create table table_data(key int, a int);
> insert into table_data values (1, 1), (2, 2), (1, 3), (2, 4), (3, 5);
> create table table_dict(key int, b int);
> insert into table_dict values (1, 42), (2, 43);
