> With  org.apache.spark.sql.functions.explode function based in the result of an  org.apache.spark.sql.functions.array the output result is not Objects inside of the object result.
> The result is an WrappedArray of one only one object and not the object itself. If we setup an scala.Array we got the result, that doesn't happens with the WrappedArray.
> myDf.withColumn("exploded_field", explode(array(my_arr_func('col_1), my_arr_func('col_2)))).take(10).foreach(println)
