Troubling Logging w/Simple Example (spark-1.2.2-bin-hadoop2.4)...

I have the following simple example program:

public class SimpleCount {

    public static void main(String[] args) {
        final String master = System.getProperty("spark.master",
"local[*]");
        System.out.printf("Running job against spark master %s ...%n",
master);

        final SparkConf conf = new SparkConf()
                .setAppName("simple-count")
                .setMaster(master)
                .set("spark.eventLog.enabled", "true");
        final JavaSparkContext sc = new JavaSparkContext(conf);

        JavaRDD<Integer> rdd = sc.parallelize(Arrays.asList(1, 2, 3, 4, 5,
6, 7, 8, 9, 10));

        long n = rdd.count();

        System.out.printf("I counted %d integers.%n", n);
    }
}

I start a local master:

export SPARK_MASTER_IP=localhost

sbin/start-master.sh


Then, I start a local worker:


bin/spark-class org.apache.spark.deploy.worker.Worker -h localhost
spark://localhost:7077



When I run the example application:


bin/spark-submit --class com.cengage.analytics.SimpleCount  --master
spark://localhost:7077
~/IdeaProjects/spark-analytics/target/spark-analytics-1.0-SNAPSHOT.jar


It finishes just fine (and even counts the right number :).  However, I get
the following log statements in the master's log file:

For such a simple example, should I be getting warnings like this?  Am I
setting up my local cluster incorrectly?

Re: Troubling Logging w/Simple Example (spark-1.2.2-bin-hadoop2.4)...

Posted by Akhil Das <ak...@sigmoidanalytics.com>.
You have an issue with your cluster setup. Can you paste your
conf/spark-env.sh and the conf/slaves files here?

The reason why your job is running fine is because you set the master
inside the job as local[*] which runs in local mode (not in standalone
cluster mode).



Thanks
Best Regards
