security exception connecting spark master java

Question

I'm new at Spark. In my project, I set master url and app name as SparkConf object.

here is my code

import org.apache.hadoop.conf.Configuration;
import org.apache.spark.SparkConf;
import org.apache.spark.api.java.JavaPairRDD;
import org.apache.spark.api.java.JavaSparkContext;
import org.bson.BSONObject;
import com.mongodb.hadoop.MongoInputFormat;
import com.mongodb.hadoop.MongoOutputFormat;

public class SparkExample {

@SuppressWarnings("resource")
public static void main(String[] args) {

    Configuration conf = new Configuration();

    conf.set("mongo.job.input.format", "com.mongodb.hadoop.MongoInputFormat");

    conf.set("mongo.input.uri", "mongodb://192.168.1.149:27017/test.sns");



    JavaSparkContext sc = new JavaSparkContext(new SparkConf().setMaster("spark://localhost:7077").setAppName("vedat"));

    JavaPairRDD<Object, BSONObject> documents = sc.newAPIHadoopRDD(conf, MongoInputFormat.class, Object.class,
            BSONObject.class);

    Configuration outConfig = new Configuration();

    outConfig.set("mongo.job.output.format", "com.mongodb.hadoop.MongoOutputFormat");

    outConfig.set("mongo.output.uri", "mongodb://192.168.1.149:27017/test.ou");

    documents.saveAsNewAPIHadoopFile("file://44", Object.class, BSONObject.class, MongoOutputFormat.class,
            outConfig);

    Configuration bsonConf = new Configuration();
    bsonConf.set("mongo.job.output.format", "com.mongodb.hadoop.BSONFileOutputFormat");

    // documents.saveAsNewAPIHadoopFile("hds://localhost:8020/user/spark/demo",
    // Object.class, BSONObject.class,
    // BSONFileOutputformat.class, bsonConf);

}

}

When I run code I get this stack trace

So, can anyone help me to show what I'm doing wrong? Why I'm getting this error?

Answer 1

Spark-core depends on: org.eclipse.jetty.orbit:javax.servlet:3.0.0.v201112011016

You should exclude it. Not sure if it's the only problem, but at least part of it if you run it inside other container.
