The textFile strategy also can take an optional 2nd argument for managing the quantity of partitions with the file. By default, Spark makes a person partition for every block of your file (blocks being 128MB by default in HDFS), but you can also request the next range of partitions by passing a bigger price. Notice that you cannot have less partitions than blocks.}
