I am managing to get everything working with the local master and two remote workers. Now, I want to connect to a remote master that has the same remote workers. I have tried different combinations of settings withing the /etc/hosts and other reccomendations on the Internet, but NOTHING worked.
The Main class is:
public static void main(String[] args) {
ScalaInterface sInterface = new ScalaInterface(CHUNK_SIZE,
"awsAccessKeyId",
"awsSecretAccessKey");
SparkConf conf = new SparkConf().setAppName("POC_JAVA_AND_SPARK")
.setMaster("spark://spark-master:7077");
org.apache.spark.SparkContext sc = new org.apache.spark.SparkContext(
conf);
sInterface.enableS3Connection(sc);
org.apache.spark.rdd.RDD<Tuple2<Path, Text>> fileAndLine = (RDD<Tuple2<Path, Text>>) sInterface.getMappedRDD(sc, "s3n://somebucket/");
org.apache.spark.rdd.RDD<String> pInfo = (RDD<String>) sInterface.mapPartitionsWithIndex(fileAndLine);
JavaRDD<String> pInfoJ = pInfo.toJavaRDD();
List<String> result = pInfoJ.collect();
String miscInfo = sInterface.getMiscInfo(sc, pInfo);
System.out.println(miscInfo);
}
It fails at:
List<String> result = pInfoJ.collect();
The error I am getting is:

Thank you kindly for your help!
Setting the environment variable SPARK_LOCAL_IP=127.0.0.1 solved this for me.
I had this problem when my /etc/hosts file was mapping the wrong IP address to my local hostname.
The BindException in your logs complains about the IP address 192.168.0.191. I assume that resolves to the hostname of your machine and it's not the actual IP address that your network interface is using. It should work fine once you fix that.
I had spark working in my EC2 instance. I started a new web server and to meet its requirement I had to change hostname to ec2 public DNS name i.e.
hostname ec2-54-xxx-xxx-xxx.compute-1.amazonaws.com
After that my spark could not work and showed error as below:
16/09/20 21:02:22 WARN Utils: Service 'sparkDriver' could not bind on port 0. Attempting port 1. 16/09/20 21:02:22 ERROR SparkContext: Error initializing SparkContext.
I solve it by setting SPARK_LOCAL_IP to as below:
export SPARK_LOCAL_IP="localhost"
then just launched sparkling shell as below:
$SPARK_HOME/bin/spark-shell
Possily your master is running on non-default port. Can you post your submit command? Have a look in https://spark.apache.org/docs/latest/spark-standalone.html#connecting-an-application-to-the-cluster
