There is no separate MapRunner in new api. You can override Mapper.run() method to achieve similar goal.

Using old API, I used to do that by setting the following: jobConf.setMapRunnerClass(ConcurrentMapper.class); ConcurrentMapper implementation is similar to how Fetcher works in Nutch. I couldn't find the similar call in the new API. If anybody knows how to do that using new API, please let me know. Thanks, Praveen
