> Took decimal_join.q and converted it to read from ORC and turned on
> vectorization:
> vector_decimal_join.q
> {code}
> SET hive.vectorized.execution.enabled=true;
> -- HIVE-5292 Join on decimal columns fails
> create table src_dec_staging (key decimal(3,0), value string);
> load data local inpath '../../data/files/kv1.txt' into table src_dec_staging;
> create table src_dec (key decimal(3,0), value string) stored as orc;
> insert overwrite table src_dec select * from src_dec_staging;
> explain select * from src_dec a join src_dec b on a.key=b.key+450;
> select * from src_dec a join src_dec b on a.key=b.key+450;
