Scala IDE 4.6.0本から入手したアーキタイプを使用して、Maven プロジェクトを使用および作成していますSpark In Action

と を使用する必要がScala 2.10.4ありSpark 1.6.2ます。

このアーキタイプを使用して基本的なプロジェクトを作成し、 に を追加しspark-hive dependencyましたPOM。結果POMは次のとおりです。

App.scalaまた、テスト用で使用していない1 つのソース ファイルもありますHive

import org.apache.spark.SparkContext
import org.apache.spark.SparkConf

object App {

def main(args : Array[String]) {
  val conf = new SparkConf().setAppName("Temp")/*.setMaster("local[*]")*/
  val sc = new SparkContext(conf)

  val col = sc.parallelize(0 to 100 by 5)
  val smp = col.sample(true, 4)
  val colCount = col.count
  val smpCount = smp.count

  println("orig count = " + colCount)
  println("sampled count = " + smpCount)
  }

}

を実行するmaven installと、次のようなエラーが発生します。

同じものを使用してPOMも、spark-hive_2.10依存関係がなければ正常に動作します。しかし、私の場合、使用してテーブルを読み取って作成したいので、依存関係sparkを使用する必要があります。spark-hive

この問題を解決するのを手伝ってくれませんか?
