Mapper, a GPS based map program uses Spark at its backend to find all specified locations within a given distance 'd' from user's current location. The program works on an RDD named coordinateRDD which contains GPS locations of a searched location type, for example 'restaurants'.

Which transform on the coordinateRDD can add a column containing distances between each of the GPS location in the RDD and the user's current location?

Which transform on the correctly returned RDD from the previous option can result in an RDD with only records that are within the given distance 'd' from the user's current location?
