Apache Spark和Java错误- 由以下原因引起：java.lang.StringIndexOutOfBoundsException：开始0，结束3，长度2

Question

我是Spark框架的新手。我试图使用spark和java创建一个示例应用程序。我有以下代码

Pom.xml

<dependency>
      <groupId>org.apache.spark</groupId>
      <artifactId>spark-core_2.10</artifactId>
      <version>1.6.1</version>
</dependency>

资源

import org.apache.spark.SparkConf;
import org.apache.spark.api.java.*;

public class SparkTest {
    public static void main(String[] args)  {
        SparkConf sparkConf = new SparkConf()
                .setAppName("Example Spark App")
                .setMaster("local[*]"); // Delete this line when submitting to a cluster
        JavaSparkContext sparkContext = new JavaSparkContext(sparkConf);
        JavaRDD<String> stringJavaRDD = sparkContext.textFile("nationalparks.csv");
        System.out.println("Number of lines in file = " + stringJavaRDD.count());
    }
}

我正在尝试使用IntelliJ IDE运行以上代码。但是我有这样的错误

我在代码中错过了什么吗？

Answer 1

您的日志中的实际错误是：

引起原因：java.lang.StringIndexOutOfBoundsException：开始0，结束3，长度2

这是由于hadoop-commonJava
9及更高版本的库中的问题。有关此错误的详细信息，请参阅https://issues.apache.org/jira/browse/HADOOP-14586。

此问题将在Spark 3.0.0发行版中修复。请参阅https://issues.apache.org/jira/browse/SPARK-26134。因此，现在您可以将Java版本降级为Java
8。
