Nifi羣集未啓動，只在一個節點

我想有兩個代理，而在第二個節點我得到以下錯誤啓動單節點集羣正在搬運工集羣上安裝Apache Nifi工作Nifi羣集未啓動，只在一個節點

我的堆棧跟蹤

發佈有關如何運行羣集的詳細信息 –

你所得到的誤差被示出，它不能實例化一個彈簧豆「protocolListener」類路徑資源定義[nifi簇 - 協議 - context.xml中]。

該bean定義是這樣的：

<!-- 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>

錯誤消息也說，問題是指數1這是getClusterNodeProtocolPort。

您很可能沒有在nifi.properties中爲此節點設置nifi.cluster.node.protocol.port。
