Related to this question, I got the tip that the getOrCreate idiom should be used to avoid this issues. But trying:

JavaStreamingContextFactory cont         


        

Answer 1

According to this question I think this is how I should do it:

SparkConf conf = new SparkConf().setAppName(NAME);
JavaSparkContext ctx = JavaSparkContext.fromSparkContext(SparkContext.getOrCreate(conf));
JavaStreamingContext context = new JavaStreamingContext(ctx, Durations.seconds(BATCH_SPAN));

Right?
