Fiware Cygnus启动错误：ClassNotFoundException

我的环境是使用CentOS 6.6的虚拟机

我按照说明书安装了天鹅座。还安装了java-1.6.0-openjdk-devel和java_主页

安装顺利，安装了cygnus.x86_64 0:0.8.2-0.g7353160包

为了测试Cygnus，我按照说明创建了agent_test.conf和notification.sh文件。当我启动Cygnus时，它会输出以下内容：

[root@localhost ~]# /usr/cygnus/bin/cygnus-flume-ng agent --conf /usr/cygnus/conf/ -f /usr/cygnus/conf/agent_test.conf -n cygnusagent -Dflume.root.logger=INFO,console

端口5050应该是正常的，因为它添加了

iptables -A INPUT -p tcp --dport 5050 -j ACCEPT

我发现了一个有点类似的问题，但这是一个更旧的版本。天鹅座0.8.2-0.g7353160应该工作吗

任何指针？

来自Cygnus 0.8.1分组机制的拦截器类型不再命名为

DestinationExtractor

，而是

GroupingInterceptor

。详细内容见（显示相关部分）：

不过，《快速入门指南》必须更新，很好

iptables -A INPUT -p tcp --dport 5050 -j ACCEPT
