我正在使用下面的Java代码读取es URL

public static void main(String[] args) {

        SparkConf sparkConf = new SparkConf(true);
        sparkConf.setappName(SparkMeasures.class.getName());
        sparkConf.setMaster("local[*]");
        sparkConf.set("spark.cleaner.ttl","3600");
        sparkConf.set("es.nodes","SMD-GUG-TC1");
        sparkConf.set("es.port","9204");
        //sparkConf.set("es.resource.read","test/doc");
        sparkConf.set("es.nodes.discovery","false");
        sparkConf.set("es.nodes.wan.only","true");
        sparkConf.set("es.field.read.empty.as.null","true");
        sparkConf.set("es.nodes.client.only","true");
        sparkConf.set("es.index.auto.create","true");
        // http://SMD-GUG-TC1:9204/patient/

        SparkSession spark = null;
        try {


            spark = SparkSession.builder().config(sparkConf).getOrCreate();
            //spark = SparkSession.builder().set.config(sparkConf).getOrCreate();
////            JavaSparkContext jsc = new JavaSparkContext(sparkConf);

            SparkContext sc = spark.sparkContext();
            JavaSparkContext jsc = JavaSparkContext.fromSparkContext(sc);
            JavaPairRDD<String,java.util.Map<String,Object>> esRDD
                    = JavaEsspark.esRDD(jsc,"patient/doc");
            esRDD.count();
        } catch (Exception e) {

            e.printStackTrace();
        }

但出现错误，
