Spark SerializedLambda错误解决方案

    在IDEA下开发Spark程序会遇到Lambda异常,下面演示异常及解决方案。

    例子

    import org.apache.spark.SparkConf;
import org.apache.spark.api.java.JavaRDD;
import org.apache.spark.api.java.JavaSparkContext;
import org.apache.spark.api.java.function.Function;

public class SimpleApp {
    public static void main(String[] args) {
        String logFile = "/soft/dounine/github/spark-learn/README.md"; // Should be some file on your system
        SparkConf sparkConf = new SparkConf()
                .setMaster("spark://localhost:7077")
                .setAppName("Demo");
        JavaSparkContext sc = new JavaSparkContext(sparkConf);
        JavaRDD<String> logData = sc.textFile(logFile).cache();

        long numAs = logData.filter(s -> s.contains("a")).count();
        long numBs = logData.map(new Function<String, Integer>() {
            @Override
            public Integer call(String v1) throws Exception {
                return 1;
            }
        }).reduce((a,b)->a+b);

        System.out.println("Lines with a: " + numAs + ", lines with b: " + numBs);

        sc.stop();
    }
}

    由于使用jdk1.8的lambda表达式，会有如下异常

    是因为jar包没有分发到Worker中。

    解决方案(一)

    添加Jar包位置路径

    SparkConf sparkConf = new SparkConf()
                .setMaster("spark://lake.dounine.com:7077")
                .setJars(new String[]{"/soft/dounine/github/spark-learn/build/libs/spark-learn-1.0-SNAPSHOT.jar"})
                .setAppName("Demo");

    解决方案(二)

    使用本地开发模式

    SparkConf sparkConf = new SparkConf()
                .setMaster("local")
                .setAppName("Demo");
