YCSB执行错误

Question

当我运行YCSB时，我得到了以下错误。我遵循了YCSB git集线器链接中指定的所有步骤，但仍然收到此错误。

我的动物园管理员跑得很好。为什么会发生这种情况？有人能在这方面帮我吗？

Answer 1

这是一个依赖问题。异常是告诉你它找不到这个方法：

org.slf4j.impl.StaticLoggerBinder.getSingleton()Lorg/slf4j/impl/StaticLoggerBinder;
//specifically 
getSingleton()

包含该方法的类是静态导入的，因此它将抛出NoSuchMethodError异常，而不是在顶层抛出NoClassDefFoundError (您可以在堆栈跟踪中看到稍后抛出)。

您需要将slf4j jar添加到类路径中。
