docker上的Nifi集群没有启动，只能在一个Node上工作
我试图在两个代理在Docker集群上安装Apache Nifi，单节点集群正在工作，同时在第二个节点上启动我得到下面的错误
我的堆栈跟踪

这个bean的定义如下所示：
<!-- protocol listener --> <bean id="protocolListener" class="org.apache.nifi.cluster.protocol.impl.SocketProtocolListener"> <constructor-arg index="0"> <bean factory-bean="nifiProperties" factory-method="getClusterNodeProtocolThreads"/> </constructor-arg> <constructor-arg index="1"> <bean factory-bean="nifiProperties" factory-method="getClusterNodeProtocolPort"/> </constructor-arg> <constructor-arg ref="protocolServerSocketConfiguration" index="2"/> <constructor-arg ref="protocolContext" index="3"/> </bean>
该错误消息还表示问题是与索引1是getClusterNodeProtocolPort。
您很可能没有在nifi.properties中为此节点设置nifi.cluster.node.protocol.port。
