查看cn-bji-p-dmp02服务器8050端口，发现此端口不通。

查看yarn-site.xml配置：

发现

  <property>
    <name>yarn.resourcemanager.address</name>
    <value>cn-bji-p-dmp02:8050</value>
  </property>
  <property>
    <name>yarn.resourcemanager.admin.address</name>
    <value>cn-bji-p-dmp02:8033</value>
  </property>
  <property>
    <name>yarn.resourcemanager.scheduler.address</name>
    <value>cn-bji-p-dmp02:8030</value>
  </property>
  <property>
    <name>yarn.resourcemanager.resource-tracker.address</name>
    <value>cn-bji-p-dmp02:8041</value>

  </property>

可能

yarn.resourcemanager.address

是由

yarn.resourcemanager.scheduler.address

的端口自动生成的。

修改成

  <property>
    <name>yarn.resourcemanager.address</name>
    <value>cn-bji-p-dmp02:8032</value>
  </property>
  <property>
    <name>yarn.resourcemanager.admin.address</name>
