java - java.lang.NoClassDefFoundError-org/apache/spark/sql/hive/HiveContext

我正在尝试使用Hive上下文，但出现以下错误：

exception: java.lang.NoClassDefFoundError: org/apache/spark/sql/hive/HiveContext

有什么建议么？

package com.mapr.examples;

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

import org.apache.spark.sql.Row;
import org.apache.spark.sql.hive.HiveContext;

import org.apache.spark.api.java.JavaRDD;
import org.apache.spark.api.java.function.*;
import org.apache.spark.sql.DataFrame;
import org.apache.spark.sql.SQLContext;
import static org.apache.spark.sql.functions.*;

import java.io.File;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

public class SparkSQLHiveContextExample {
    public static void main(String[] args) throws Exception {
        SparkConf sparkConf = new SparkConf().setAppName("SparkSQLHiveContextExample");
        JavaSparkContext ctx = new JavaSparkContext(sparkConf);

        // SQLContext sqlContext = new HiveContext(ctx); // exception: java.lang.NoClassDefFoundError: org/apache/spark/sql/hive/HiveContext
        // HiveContext hiveContext = new HiveContext(ctx.sc()); // exception: java.lang.NoClassDefFoundError: org/apache/spark/sql/hive/HiveContext
        // HiveContext hiveContext = new org.apache.spark.sql.hive.HiveContext(ctx.sc()); // exception: java.lang.NoClassDefFoundError: org/apache/spark/sql/hive/HiveContext


        ctx.stop();
        ctx.close();

    }
}

最佳答案

添加此依赖项后，您可以尝试吗？

它应该工作。
