mapreduce测试时出现INFO client.RMProxy: Connecting to ResourceManager at 0.0.0.0:8032后无响应问题，可能是没有配置好yarn-site.xml()

如运行wordcount后出现INFO client.RMProxy: Connecting to ResourceManager at 0.0.0.0:8032长时间不动，我尝试修改我的yarn-site.xml配置后可以成功运行

   <property>     <name>yarn.nodemanager.aux-services</name>     <value>mapreduce_shuffle</value>   </property>   <property>      <name>yarn.resourcemanager.address</name>      <value>centos01:8032</value>   </property>   <property>     <name>yarn.resourcemanager.scheduler.address</name>     <value>centos01:8030</value>  </property>  <property>    <name>yarn.resourcemanager.resource-tracker.address</name>    <value>centos01:8031</value>  </property>  <property>    <name>yarn.resourcemanager.admin.address</name>    <value>centos01:8033</value>  </property>  <property>    <name>yarn.resourcemanager.webapp.address</name>    <value>centos01:8088</value>  </property>  <property>    <name>yarn.nodemanager.vmem-pmem-ratio</name>    <value>2.8</value>  </property></configuration>
