启动YARN的ResourceManager时遇到闪退问题，通过查看日志发现是由于配置错误导致。具体错误信息为：Embedded automatic failover is enabled, 但yarn.resourcemanager.zk-address未设置。解决方法是正确配置yarn.resourcemanager.zk-address。" 130550757,11183300,Matlab中BWO-BiLSTM模型优化数据分类预测,"['数据分类预测', 'BWO-BiLSTM', 'matlab编程', '神经网络', '机器学习']

执行命令start-yarn.sh 和 yarn-daemon.sh start resourcemanager，发现resourcemanager启动不了。
然后查询log，发现原来是配置文件有错误。

错误配置：

<property>
  <name>yarn.resourcemanager.zk.address</name>
  <value>hadoop01:2181,hadoop02:2181,hadoop03:2181</value>
</property>

正确配置：

<property>
  <name>yarn.resourcemanager.zk-address</name>
  <value>hadoop01:2181,hadoop02:2181,hadoop03:2181</value>
</property>
