我正在使用azure vnet中的azure函数生成一个火花集群。每个火花节点都位于单独的Azure容器实例组中。 这是它的工作方式： 我生成一个主节点ACI组并获取其IP地址，然后生成一个从属节点ACI组。我在生成工作程序时传递主节点的IP地址。 但是，我面临的问题是-如果我使用spark提交作业，则该作业无法完成，并且出现以下错误：

经过大量研究，我发现我必须对集群中所有节点的每个节点的/ etc / hosts文件进行输入 类似于以下内容：
10.0.0.4 spark-master
10.0.0.5 spark-worker-1
10.0.0.6 spark-worker-2
10.0.0.7 spark-driver
我手动进行了上述输入，然后作业成功执行。
但是，我如何以编程方式（使用azure函数本身）进行上述输入，即如何获取集群中每个节点的IP地址和主机名，并在/ etc /中为每个节点进行输入在运行Azure容器实例之后，每个其他节点的主机文件吗？
