CoalescedRDDPartition

case class CoalescedRDDPartition(index: Int, rdd: RDD[_], parentsIndices: Array[Int], preferredLocation: String = "") extends Partition with Product with Serializable

Class that captures a coalesced RDD by essentially keeping track of parent partitions

index

of this coalesced partition

rdd

which it belongs to

parentsIndices

list of indices in the parent that have been coalesced into this partition

preferredLocation

the preferred location for this partition
