spark 0.9.0 saveAsTextFile gives classnotfound error
Running code outside spark shell give following . Same code works fine within
spark shell.
Here is simple code.
object zyz extends Serializable {
def main(args: Array[String]) {
val sc = new SparkContext(args(0), "Knn ",
System.getenv("SPARK_HOME"), Seq(System.getenv("SPARK_APP_JAR")))
val knnInput = if (args.length > 1) args(1) else
"/user/root/input/test1.dat"
val outputpath = if (args.length > 2) args(2) else
"/user/root/output/knn"
val approxmateSize = if (args.length > 3) args(3).toInt else 10
var partition = 3
if (approxmateSize >= 10000) {
partition = approxmateSize / 100
}
val data = sc.textFile(knnInput)
val data1 = data.map(x => {
val pt = x.split(",")
val zie = pt.length
var arr = new scala.collection.mutable.ArrayBuffer[Double]()
for (i <- 1 until zie) {
arr += pt(i).toDouble
}
(scala.util.Random.nextInt(partition), (pt(0), arr))
})
data1.saveAsTextFile(outputpath)

following error is shown.

Any idea.
I am running this build using mvn.
Any help will be appreciated.
