Spark Java saveAsTable schlägt mit ArrayIndexOutOfBoundsException fehl

Ich verwende 2.4.0 Spark-Core und Spark-SQL.

Ich versuche SparkSession zu erstellen und dann einen Bereich zu erstellen und ihn dann in die Tabelle zu schreiben.

Mit Scala funktioniert folgender Code

val sparkSession = SparkSession
  .builder()
  .appName("Java Spark SQL basic example")
  .config("spark.master", "local")
  .getOrCreate();
   sparkSession.range(10).write.option("path", "/tmp/test").saveAsTable("testData")

Wenn ich jedoch dieselben Schritte mit Java durchführe, schlägt dies fehl.

   SparkSession sparkSession = SparkSession.builder()
            .appName("Java Spark SQL basic example")
            .config("spark.master", "local")
            .getOrCreate();

    //create table
    sparkSession.range(10).write().mode(SaveMode.Overwrite).option("path", "/tmp/test").saveAsTable("testData");

Die Fehlerstack-Ablaufverfolgung lautet:

Es ist ein Problem mit der Paranamer-Version. Fügen Sie folgende Abhängigkeit vor dem Spark-Core/Spark-SQL hinzu.

<dependency>
    <groupId>com.thoughtworks.paranamer</groupId>
    <artifactId>paranamer</artifactId>
    <version>2.8</version>
</dependency>

Versuche dies:

 sparkSession.range(10).write().mode("append").insertInto("testData");

antwort ist <groupId>org.Apache.spark</groupId> <artifactId>spark-core_2.11</artifactId> <version>2.2.0</version> </dependency> Sie verwenden nicht 2.4.0 Spark-core und Spark-sql. denn es ist nicht stabil
