未绑定到浮动IP的Spark群集主IP地址

Question

null

当我尝试使用这些浮动IPs和标准公共IPs时，我遇到了问题。

在spark-master计算机上，主机名为spark-master，/etc/hosts类似于

127.0.0.1 localhost
127.0.1.1 spark-master

对spark-env.sh所做的唯一更改是export spark_master_ip='192.x.x.1'。如果我运行./sbin/start-master.sh，我可以查看web UI。

Spark Command: /usr/lib/jvm/java-7-openjdk-amd64/bin/java -cp /usr/local/spark-1.6.1-bin-hadoop2.6/conf/:/usr/local/spark-1.6.1-bin-hadoop2.6/lib/spark-assembly-1.6.1-hadoop2.6.0.jar:/usr/local/spark-1.6.1-bin-hadoop2.6/lib/datanucleus-core-3.2.10.jar:/usr/local/spark-1.6.1-bin-hadoop2.6/lib/datanucleus-api-jdo-3.2.6.jar:/usr/local/spark-1.6.1-bin-hadoop2.6/lib/datanucleus-rdbms-3.2.9.jar -Xms1g -Xmx1g -XX:MaxPermSize=256m org.apache.spark.deploy.master.Master --ip 87.x.x.1 --port 7077 --webui-port 8080

您的主机名spark-master解析为环回地址：127.0.1.1；使用192.x.x.1代替（在接口eth0)16/05/12 15:05:33警告UTILS：如果需要绑定到另一个地址，请设置SPARK_LOCAL_IP

但无论我尝试采取什么方法，我都会遇到更多的错误。

如果我同时设置export spark_master_ip='87.x.x.1'和export spark_local_ip='87.x.x.1'并尝试./sbin/start-master.sh，我会得到以下错误日志

Answer 1

我自己在Openstack上设置了一个spark集群（独立集群），在主服务器上的/etc/hosts文件中，我有：

127.0.0.1本地主机

192.168.1.2火花主控器，而不是127.0.0.1
