partitionAndJoin(baseRDD: RDD[(ReferenceRegion, T)], joinedRDD: RDD[(ReferenceRegion, U)]): RDD[(Option[T], U)]
Performs a right outer region join between two RDDs.
Performs a right outer region join between two RDDs.
- baseRDD
The 'left' side of the join
- joinedRDD
The 'right' side of the join
- returns
An RDD of pairs (Option[x], y), where the optional x value is from baseRDD, y is from joinedRDD, and the region corresponding to x overlaps the region corresponding to y. If there are no keys in the baseRDD that overlap a given key (y) from the joinedRDD, x will be None.
