将边缘节点配置为在专用网络上运行的群集上启动Hadoop作业

我正在尝试将边缘节点设置到工作场所的群集。集群是CDH 5.*Hadoop纱线。它有自己的内部专用高速网络。边缘节点位于专用网络之外

我运行了hadoop客户端设置步骤，并配置了核心站点.xml
sudoapt-get安装hadoop客户端

由于集群托管在自己的专用网络上，因此内部网络中的IP地址不同。 10.100.100.1-名称模式 10.100.100.2-数据节点1 10.100.100.4-数据节点2 100.100.100.6-日期节点3

为了处理这个问题，我请求集群管理员将以下属性添加到namenode上的hdfs-site.xml中，以便侦听端口不只是对内部IP范围开放：

<property>
  <name>dfs.namenode.servicerpc-bind-host</name>
  <value>0.0.0.0</value>
</property>
<property>
  <name>dfs.namenode.http-bind-host</name>
  <value>0.0.0.0</value>
</property>
<property>
  <name>dfs.namenode.https-bind-host</name>
  <value>0.0.0.0</value>
</property>
<property>
  <name>dfs.namenode.rpc-bind-host</name>
  <value>0.0.0.0</value>
</property>

同一错误消息重复多次

为了安全起见，我从集群数据节点复制了其余的xml，即hdfs-site.xml、warn-site.xml、mapred-site.xml。但我还是犯了同样的错误。有没有人知道这个错误，或者如何让边缘节点在运行在专用网络上的集群上工作

边缘节点的用户名为“administrator”，而群集是使用“hduser”id配置的。这可能是个问题吗？我已经在边缘节点和名称节点之间配置了无密码登录
