Hi,

I am wondering if it is possible to get the partition position of cached RDD? I am asking this because I am trying to avoid shuffling when performing coalesce operation. And the size of my partitions could be quite imbalance thus CoalescedRDD would probably not be a good solution in my case.

Thank you!

Best,
Wenlei
