Q:

Java Job Failed to Connect to Standalone Local Master

I am new to spark and have been trying to run my first java spark job through a standalone local master.
Now my master is up and one worker gets registered as well, but when run below spark program I got org.apache.spark.SparkException: Exception thrown in awaitResult.
My program should work as it runs fine when master is set to local.
My Spark Code:
public static void main(String[] args) {

    //Setup configuration
    String appName = "My Very First Spark Job";
    //String sparkMaster = "local[2]";
    String sparkMaster = "spark://10.0.0.116:7077";

    JavaSparkContext spContext = null;

    SparkConf conf = new SparkConf()
            .setAppName(appName)
            .setMaster(sparkMaster);

    //Create Spark Context from configuration
    spContext = new JavaSparkContext(conf);

Logs:

A:

I faced the same problem when trying to connect to the local cluster from my eclipse dev environment.
In my case it was version mismatch with master and with my development environment, where I was using maven dependencies.
Cluster was : 2.2.1
My dev was :  2.1.0
Once I corrected the version, error was resolved.
