If you are using Spark-sql as opposed to spark-shell, then you can just use
UNION as in SQL for this. Pretty straight forward.
SELECT * from TABLE_A
UNION
SELECT * from TABLE_B
ORDER BY COLUMN_A, COLUMN_B;
Example
spark-sql> SELECT * FROM dummy where id = 1
> UNION
> SELECT * FROM dummy2 where id = 10
> ORDER by id;
