WSO2 Enterprise Integrator 6.0.0 无法找到 snappy-java jar

Question

按照快速入门指南
https://docs.wso2.com/display/EI600/Quick+Start+Guide

由于我使用的是 Windows，我已经下载了 snappy-java 并放入\wso2\analytics\lib
但是在启动EI分析时仍然出现如下异常

我怀疑指南将 jar 放置在不正确的路径中，在以前的 ESB 5.0.0 版本中，路径在\repository\components\lib

正确的路径是 EI_HOME\lib 。当您看到“正在启动轮询事件接收器”并且没有出现错误时，它可以工作。然后你可以继续。 :)
