org.apache.nifi.web.NiFiCoreException：无法启动Flow Controller

时间：2018-08-21 20:34:19

标签： apache-nifi

我正在设置一个由3个节点组成的NiFi 1.7.1版本构建集群。 我正在为Zookeeper使用其他3个节点（不使用嵌入式zk） 使用Java 1.8 build 181

使用外部Zookeeper以群集模式启动Nifi时出现此错误

引起异常的最初原因是Error creating bean with name 'protocolListener' defined in class path resource [nifi-cluster-protocol-context.xml]: Unsatisfied dependency expressed through constructor parameter 1: Could not convert argument value of type [null] to required type [int]: ...的{​​{1}}参数1（ second 参数）是protocolListener：

clusterNodeProtocolPort

在 <!-- 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> 文件中，您应该具有：nifi.properties或其他端口号。我猜您的nifi.cluster.node.protocol.port=11443中该字段为空。请记住在每个节点上进行设置，并确保端口在同一台计算机上运行时不会发生冲突。

确保每个节点上的所有Zookeeper设置都正确。
