ClassNotFoundException: com.datastax.spark.connector.rdd.partitioner.CassandraPartition

问题

I am using

Spark version 2.2.1
Using Scala version 2.11.8
OpenJDK 64-Bit Server VM, 1.8.0_131

I have add jar dependency by using code

JavaSparkContext sc = new JavaSparkContext(conf);
        sc.addJar("./target/CassandraSparkJava-1.0-SNAPSHOT-jar-with-dependencies.jar");

Executing below code, but facing ClassNotFoundException:com.datastax.spark.connector.rdd.partitioner.CassandraPartition

Dataset<org.apache.spark.sql.Row> dataset = sparksession.read().format("org.apache.spark.sql.cassandra")
            .options(new HashMap<String, String>() {
                {
                    put("keyspace", "test_db");
                    put("table", "stats");
                }
            }).load().where("timestamp = '2018-01-09 00:00:00'");
    System.out.println(" Result " + dataset.collectAsList().size());
