Spark群集主IP地址未绑定到浮动IP

Question

我正在尝试使用OpenStack配置Spark集群.目前我有两个名为的服务器

• spark-master(IP:192.xx1,浮动IP:87.xx1)
• spark-slave-1(IP:192.xx2,浮动IP:87.xx2)

尝试使用这些浮动IP与标准公共IP时,我遇到了问题.

在spark-master机器上,主机名是spark-master,而/ etc/hosts看起来像

127.0.0.1 localhost
127.0.1.1 spark-master

对spark-env.sh进行的唯一更改是export SPARK_MASTER_IP='192.x.x.1'.如果我运行,./sbin/start-master.sh我可以查看Web UI.

问题是我使用浮动IP 87.xx1查看Web UI,并在其中列出主URL:spark://192.xx1:7077.

从奴隶我可以运行./sbin/start-slave.sh spark://192.x.x.1:7077,它成功连接.

如果我尝试通过更改主服务器上的spark-env.sh来使用浮动IP,export SPARK_MASTER_IP='87.x.x.1'那么我会得到以下错误日志

显然,对我来说这里的内容就是这条线

您的主机名spark-master解析为环回地址:127.0.1.1; 使用192.xx1代替(在接口eth0上)16/05/12 15:05:33 WARN实用程序:如果需要绑定到另一个地址,请设置SPARK_LOCAL_IP

但无论采用何种方法,我都会尝试采取更多错误.

如果我设置两个export SPARK_MASTER_IP='87.x.x.1'并export SPARK_LOCAL_IP='87.x.x.1'尝试./sbin/start-master.sh我得到以下错误日志

尽管事实上我的安全组似乎是正确的

Answer 1

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

127.0.0.1 本地主机

192.168.1.2 火花大师代替 127.0.0.1

现在，由于我有一个供主设备和从设备使用的虚拟专用网络，因此我只使用专用 IP。我唯一一次使用浮动IP是在我的主机上启动spark-submit --master spark://spark-master（这里的spark-master解析为浮动IP）。我认为你不需要尝试绑定浮动IP。我希望这有帮助！

Answer 2

正如日志中所示，

您的主机名 Spark-master 解析为环回地址：127.0.1.1；使用 192.xx1 代替（在接口 eth0 上）

Spark自动尝试获取主机的IP，并且它使用其他IP192.x.x.1而不是浮动IP87.x.x.1

要解决这个问题，你应该设置SPARK_LOCAL_IP=87.x.x.1（最好在spark-env.sh中）并再次启动你的master
