value join is not a member of org.apache.spark.rdd.RDD

[Shay Seng]

Hi,
I'm having some problem getting a piece of code that I can run in the REPL
to compile....

val aDay = day.map( n=>
   ...
  ((aInt,bInt),(cInt,dInt,eDbl,fInt,gDbl))
)

val seg = segments.map( n =>
 ...
 ((aInt,bInt), (......))
)

val allSegs = aDay.join(seg)

error: value join is not a member of org.apache.spark.rdd.RDD[((Int, Int),
(Int, Int, Double, Int, Double))]

How do I make aDay a PairRddFunctions ?
