Is it possible to repartition an existing RDD which is already partioned ?


@Sudharsan Ganeshkumar

Yes, you can repartition the rdd which is already partitioned. Just use .repartition

@Sandeep Nemuri Ya, i m able to use repartition for a different RDD. Is it possible to repartition the same RDD ?

RDD are immutable so when you repartition or coalesce it always creates a new RDD. When possible it's preferred to use coalesce since it could avoid shuffling (which is always expensive task). You can read more here:
