Java Hadoop3:连接到ResourceManager的工作节点错误

我有一个3节点的hadoop集群（DigitalOcean）：

• hadoop主机配置为namenode和datanode
• hadoop-worker1和hadoop-worker2配置为数据节点

每当我运行mapreduce流作业并且选择工作节点来运行ApplicationMaster时，该作业将在尝试连接到ResourceManager时挂起。datanode日志显示它试图连接到0.0.0.0

INFO [main] org.apache.hadoop.yarn.client.RMProxy: Connecting to ResourceManager at /0.0.0.0:8030
INFO [main] org.apache.hadoop.ipc.Client: Retrying connect to server: 0.0.0.0/0.0.0.0:8030. Already tried 0 time(s);
INFO [main] org.apache.hadoop.ipc.Client: Retrying connect to server: 0.0.0.0/0.0.0.0:8030. Already tried 1 time(s);

这是

warn.resourcemanager.hostname属性的默认值。
但是，我已在Thread-site.xml中为我的两个工作节点指定了此属性：

<property>
   <name>yarn.resourcemanager.hostname</name>
   <value>hadoop-master</value>
</property>

我还通过转到hadoop-worker1:9864并访问worker节点的web界面查看加载的内容来检查配置：

<property>
<name>yarn.resourcemanager.hostname</name>
<value>hadoop-master</value>
<final>false</final>
<source>yarn-site.xml</source>
</property>

我不确定该怎么办，我相信这可能与流媒体作业没有正确加载设置有关，任何帮助都将不胜感激，因为我已经在这个问题上被困了2天。
我已经将
-D纱线.resourcemanager.hostname=hadoop master
标志添加到mapred流式处理命令中，现在似乎可以工作了。
我已经将
-D纱线.resourcemanager.hostname=hadoop master
标志添加到mapred流式处理命令中，并且它现在似乎起作用了

<final>false</final>
<source>yarn-site.xml</source>
</property>
