java.net.BindException: Problem binding to [master:8032] java.net.BindException: Address already in use

今天在搭完全分布式的时候  resourcemanager一直起不来，然后去看日志

意思是端口被占用，然后我就用 netstat 命令去找相关端口  我看了端口也没有被占用

然后就去查配置   发现是里面配置的两个服务的端口一样  所以导致起不来

下面是正确的 yarn-site.xml 的配置

<property>
	<name>yarn.resourcemanager.hostname</name>
	<value>master</value>
</property>
<property>
	<name>yarn.nodemanager.aux-services</name>
	<value>mapreduce_shuffle</value>
</property>
<property>
	<name>yarn.resourcemanager.address</name>
	<value>master:8032</value>
</property>
<property>
	<name>yarn.resourcemanager.scheduler.address</name>
	<value>master:8030</value>
</property>
<property>
	<name>yarn.resourcemanager.resource-tracker.address</name>
	<value>master:8031</value>
</property>
<property>
	<name>yarn.resourcemanager.admin.address</name>
	<value>master:8033</value>
</property>
<property>
	<name>yarn.resourcemanager.webapp.address</name>
	<value>master:8088</value>
</property>

出错看日志，日志看不懂就先去看配置，一定是这两个地方出错了

另外，有Hadoop及其相关组件出错的地方欢迎打扰 微信：byf34527655
