如何在Apache-Spark中连接主站和从站？(独立模式)

Question

我正在使用Spark Standalone Mode教程页面以独立模式安装Spark.

1-我通过以下方式开始了一个大师:

./sbin/start-master.sh

2-我通过以下方式创办了一名工人:

./bin/spark-class org.apache.spark.deploy.worker.Worker spark://ubuntu:7077

注意:spark://ubuntu:7077是我的主人名,我可以在其中看到Master-WebUI.

问题:通过第二个命令,工作人员成功启动.但它无法与主人联系.它反复尝试,然后给出这个消息:

15/02/08 11:30:04 WARN Remoting: Tried to associate with unreachable    remote address [akka.tcp://sparkMaster@ubuntu:7077]. Address is now gated for 5000 ms, all messages to this address will be delivered to dead letters. Reason: Connection refused: ubuntu/127.0.1.1:7077
15/02/08 11:30:04 INFO RemoteActorRefProvider$RemoteDeadLetterActorRef: Message [org.apache.spark.deploy.DeployMessages$RegisterWorker] from Actor[akka://sparkWorker/user/Worker#-1296628173] to Actor[akka://sparkWorker/deadLetters] was not delivered.

15/02/08 11:31:15 ERROR Worker: All masters are unresponsive! Giving up.

问题是什么？

谢谢

Answer 1

我通常从spark-env.sh模板开始.我设置了我需要的属性.对于简单群集,您需要:

• SPARK_MASTER_IP

然后,在与spark-env.sh和slave ip(每行一个)相同的目录中创建一个名为"slaves"的文件.保证你通过ssh到达所有奴隶.

最后,在群集的每台计算机中复制此配置.然后启动整个集群执行start-all.sh脚本并尝试使用spark-shell检查配置.

> sbin/start-all.sh
> bin/spark-shell
