问题
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!
回答1:
Setting the environment variable SPARK_LOCAL_IP=127.0.0.1 solved this for me.
回答2:
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.
回答3:
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
