工人：无法连接到主站的火花阿帕奇

我尝试部署使用独立的集群管理器Windows上的应用程序星火，所以在主端（IP：192。 .186），我跑：工人：无法连接到主站的火花阿帕奇

\bin>spark-class org.apache.spark.deploy.master.Master

，并在从站侧（IP：192. 0.75）我跑：

\bin>spark-class org.apache.spark.deploy.worker.Worker spark://192.*.*.186:7077

我有一个问题，第e客户端无法连接到主节点，这是我得到的错误：

测试两台机器之间的连接？ –

bin>spark-class org.apache.spark.deploy.worker.Worker spark://192.*.*.186:7077

上述命令中提到的master-ip是否正确？

你写道，主ip是192 ... 168，但在奴隶启动命令你用192尝试。。。，错字：6和8倒转

好的，那么你可以尝试使用以下命令从slave box到master进行telnet。 > telnet master-ip 7077 –

此外，在文件中添加以下行：SPARK_HOME/conf/spark-env.sh 'SPARK_MASTER_IP = 192 ... 186' 然后重新启动工作站或主站中的火花主站 –
