问题描述
我使用教程页面安装星火在独立模式。
I'm using Spark Standalone Mode tutorial page to install Spark in Standalone mode.
1 - 我已经开始主：
1- I have started a master by:
./sbin/start-master.sh
2 - 我已经开始了一个工人：
2- I have started a worker by:
./bin/spark-class org.apache.spark.deploy.worker.Worker spark://ubuntu:7077
请注意：火花：// Ubuntu的：7077 是我的主人的名字，这是我可以看到它在主WebUI中。
Note: spark://ubuntu:7077 is my master name, which I can see it in Master-WebUI.
问题：按第二个命令，一名工人成功启动。但它无法与主人联系起来。它反复尝试，然后把这个消息：
Problem: By second command, a worker started successfully. But it couldn't associate with master. It tries repeatedly and then give this message:
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

这是什么问题？
感谢
推荐答案
我通常的模板。我设置，我需要的属性。对于简单的集群，您需要：
I usually start from spark-env.sh template. And I set, properties that I need. For simple cluster you need:
- SPARK_MASTER_IP
然后，创建一个名为奴隶在同一目录文件作为spark-env.sh和奴隶的ip的（每行一个）。向你保证，通过ssh到达所有的奴隶。
Then, create a file called "slaves" in the same directory as spark-env.sh and slaves ip's (one per line). Assure you reach all slaves through ssh.
最后，群集中的每个机器复制该配置。。然后启动整个集群执行start-all.sh脚本，并尝试火花外壳，检查您的配置。
Finally, copy this configuration in every machine of your cluster. Then start the entire cluster executing start-all.sh script and try spark-shell to check your configuration.
> sbin/start-all.sh
> bin/spark-shell
