Subject About implicit rddToPairRDDFunctions
Date Thu, 06 Nov 2014 11:12:37 GMT
I saw many people asked how to convert a RDD to a PairRDDFunctions. I would
like to ask a question about it. Why not put the following implicit into
"pacakge object rdd" or "object rdd"?

  implicit def rddToPairRDDFunctions[K, V](rdd: RDD[(K, V)])
      (implicit kt: ClassTag[K], vt: ClassTag[V], ord: Ordering[K] = null)
= {
    new PairRDDFunctions(rdd)

If so, the converting will be automatic and not need to
import org.apache.spark.SparkContext._

I tried to search some discussion but found nothing.

Best Regards,
Shixiong Zhu
