I am trying to run simple code e.g
public class SimpleApp {
public static void main(String[] args) throws InterruptedException {
SparkConf conf = new SparkConf().setAppName("Simple Application").
setMaster("spark://master.genpact.com:7078").set("spark.eventLog.enabled", "true");
File tempDir=Files.createTempDir();
tempDir.deleteOnExit();
JavaSparkContext sc = new JavaSparkContext(conf);
java.util.List<String> strings = Arrays.asList("Hello", "World");
JavaRDD<String> s1 = sc.parallelize(strings);
JavaRDD<String> s2 = sc.parallelize(strings);
// Varargs
JavaRDD<String> sUnion = sc.union(s1, s2);
System.out.println("Union *******"+sUnion.collect());
}
}
