私は分散コンピューティングの新機能です。私はローカルマシン上でSpark 2.2で同様のコードを実行することができます。今私はJavaで同じことをしようとしており、私はこれを得続けるerror。私はJavaSparkContextを作成し、このオブジェクトを自分のコードで使用することができます.Issueはビルダーを使用してSparkSessionを作成するときです。 私のローカル環境である：、2.2を窓7スパーク、Javaの1.8Java 1.8とSpark2.2を使用したSparkSessionの作成
マイコードは、私は、依存関係を管理するためにMavenを使用しています
public static void main(String[] args) {
SparkConf sparkConf = new SparkConf();
sparkConf.setAppName("Java-Spark");
sparkConf.setMaster("local");
SparkSession sc= SparkSession.builder().appName("test").master("local[*]").config("spark.driver.cores", 1).getOrCreate();
/* this commented code works fine.
JavaSparkContext context = new JavaSparkContext(sparkConf);
JavaRDD<Integer> numbersRDD = context.parallelize(Arrays.asList(1,2,3));
JavaRDD<Integer> squaresRDD = numbersRDD.map(n -> n*n);
System.out.println("1 :");
System.out.println(squaresRDD.collect().toString());
JavaRDD<Integer> evenRDD = squaresRDD.filter(n -> n%2==0);
System.out.println("2 :");
System.out.println(evenRDD.collect().toString());
JavaRDD<Integer> multipliedRDD = numbersRDD.flatMap(n->Arrays.asList(n,n*2,n*3).iterator());
System.out.println("3 :");
System.out.println(multipliedRDD.collect().toString());
context.close();
*/
sc.close();
}
のように見えます。 pom.xmlは、私は最後の2日間からこのエラーに苦しんでいると私がここで行方不明ですかを把握することはできません

'mvn dependency：tree'コマンドを実行して出力してください。 ANTLRライブラリの2つの相反するバージョンを見つけることができます。 –
'spark-sql_2.11'以外のすべての依存関係を削除し、やり直してください。 'pom.xml'にはdepsが多すぎますので、それを少しきれいにしましょう。 –
Jacek Laskowskiが提案したように、私はpom.xmlをきれいにしてspark-sql_2.11を追加しました。結果：元の質問と同じエラーが報告されました。 –
