一、MRUnit测试jar包mrunit-1.1.0-hadoop2.jar第三方依赖MRUnit\apache-mrunit-1.1.0-hadoop1-bin\lib二、在现有工程里面配置MRUnit单元测试1、新建一个userlib2、将MRUnitLib添加到mr工程,如下图:3、解决jar包冲突由于在MRUnitLib包中存在mockito-core-1.9.5.jar包,该包和E:\d MapReduce MRunit 测试 ...
MRUnit is a unit test library designed to facilitate easy integration between your MapReduce development process and standard development and testing tools such as JUnit. MRUnit contains mock objects that behave like classes you interact with during MapReduce execution (e.g., InputSplit and OutputC...

MRUnit简介 官网地址:https://mrunit.apache.org/ Apache MRUnit ™ is a Java library that helps developers unit test Apache Hadoop map reduce jobs. MRUnit是一个帮助开发者测试map reduce 作业的单元测试库。 代码示例 以maven项目为例,演示如何使用MRUnit进行MR单元测试。
JavaRDD data3 = doSomethingWithAReduce(data2); Coming from MRUnit If you’re coming from an MRUnit background, I want to point out a few differences. One big difference is how Spark is started. With MRUnit, the entire framework wasn’t started, withspark-testing-base, Spark is started...
在完成正确的导入（基本上是powermock版本1.5.1及其junit活页夹）之后，我解决了这个问题。
