$locate zookeeper

您能解释一下我在想什么吗?
关键似乎在这里:
Caused by: java.lang.ClassNotFoundException: org.apache.zookeeper.server.NIOServerCnxn$Factory
这似乎是由于使用的版本引起3.4.5
的zookeeper
。您是否尝试过降级到版本3.3.6
?
分支3.3包含嵌套类NIOServerCnxn
$厂
,但分支3.4有NIOServerCnxnFactory代替
要开发 topology, 您将需要您的类路径上的 Storm jar. 您应该在项目的类路径中包含未打包的 jar, 或者使用 Maven 将 Storm 包含为开发依赖项. Storm 托管在 Maven Central. 要将 Storm 作为开发依赖项包含在项目中, 请将以下内容添加到 pom.xml 中: <dependency> <groupId>org.apache.storm
当我试图创建一个Cordova PhoneGap应用程序时,在最后一步中,当我使用build命令时,我得到了这个错误 我得到了这个错误:

要配置,它需要,而BrokerHosts又需要一个动物园管理员主机。 问题是,如果我有一个zookeeper仲裁(由3个zk服务器组成的集群),我如何配置KafkaSpout以获取仲裁的所有成员,而不是仅1个。因为一个zookeeper服务器可能会停机,整个拓扑将不可用。
谁能帮我在windows中如何将storm与zookeeper集成。 我试图找到一个好的安装步骤生产在窗口,但我不能。 现在写我已经安装了独立的zookeeper,我正在尝试在Storm中配置它。yaml。 我尝试的示例代码: 如果有人知道,请帮助我。
