在有两个inet的机器上设置一个spark集群，一个公用，另一个专用。集群中的/etc/hosts文件具有集群中所有其他计算机的内部ip，如下所示。
内部ip fqdn
但是，当我在客户机模式下通过pyspark请求sparkcontext时( pyspark --master yarn --deploy-mode client )，akka绑定到公共ip，因此发生超时。

群集是使用ambari（hdp2.4）配置的

这是目前spark中的一个问题，让spark绑定到正确接口的唯一方法是使用自定义名称服务器。
spark基本上进行主机名查找，并使用找到的ip地址与akka绑定。解决方法是创建自定义绑定区域并运行名称服务器。

+问题是1。
spark使用akka进行通信。
所以这更像是一个阿克卡问题而不是Spark。
如果需要将网络接口绑定到其他地址，请使用akka.remote.netty.tcp.bind-hostname和akka.remote.netty.tcp.bind-port设置。
