Java 使用CQLOutputformat从hadoop写入时，Cassandra群集提供连接被拒绝错误

我有一个单节点cassandra集群，它没有与我的hadoop集群共存。我使用这个hadoop集群使用CqlOutputFormat和以下作业配置将数据批量加载到Cassandra集群中

    Job job = new Job(conf);
    Configuration jobConf = job.getConfiguration();
    ConfigHelper.setOutputInitialAddress(jobConf, "10.27.124.73");
    ConfigHelper.setInputInitialAddress(jobConf, "10.27.124.73");
    //ConfigHelper.setOutputRpcPort(jobConf, "9160"); I tried setting the ports. Doesn't help. 
    //ConfigHelper.setInputRpcPort(jobConf, "9160");
    ConfigHelper.setOutputPartitioner(jobConf,"Murmur3Partitioner");
    ConfigHelper.setInputPartitioner(jobConf, "Murmur3Partitioner");
    ConfigHelper.setInputColumnFamily(jobConf, "pinspace", "pinseries");

    ConfigHelper.setOutputColumnFamily(jobConf, "pinspace", "pinseries");
    System.out.println(ConfigHelper.getOutputColumnFamily(jobConf));

    String query = "update pinspace.pinseries set timeseries = ?";

    CqlConfigHelper.setOutputCql(jobConf, query);
    CqlConfigHelper.setInputCQLPageRowSize(jobConf, "3");

    job.setInputFormatClass(BoomInputFormat.class);
    job.setMapperClass(GrepMapper.class);

    job.setOutputKeyClass(Text.class);
    job.setOutputValueClass(IntWritable.class);

    job.setReducerClass(GrepReducer.class);
    job.setNumReduceTasks(1024);
    job.setOutputFormatClass(CqlOutputFormat.class);

我收到以下stacktrace的连接被拒绝错误：

我使用的是cassandra驱动核心2.1.5和cassandra全部2.1.3

服务器可以使用来自datanodes和telnet 10.27.124.73 9160以及telnet 10.27.124.73 9042的给定IP进行ping

编辑：

我试着在代码中使用， setOutpurtPCPort（jobConf，“9042”）

然后错误更改为：
