无法绑定到:spark-master，使用具有两个工作人员的远程集群 [英] Failed to bind to: spark-master, using a remote cluster with two workers

问题描述

我正在设法让本地主服务器和两个远程工作人员能够正常工作.现在，我想连接到具有相同远程工作者的远程主机.我已经尝试使用/etc/hosts 和 Internet 上的其他建议进行不同的设置组合，但没有任何效果.

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.

主类是:

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);

}

失败:

List<String> result = pInfoJ.collect();

我得到的错误是:
