补充一下我是根据御膳房文档中“MR&UDF本地开发工具”文章（链接我发不了。。），运行的是样例Word Count（程序在创建完project就有的）

-------------------------

我就是按照那个配置的，那个貌似并没有安装odps sdk

-------------------------

而且如果我把Combiner在base.mapred.xml里面去掉，会得到这个错误：

Exception in thread "main" java.lang.RuntimeException: java.lang.UnsupportedOperationException: ODPS-0720503:Unexpected intermediate output in mapper, it is only allowed in mapreduce (reduce num > 0) jobs

把 numReduceTask 设成1 可以跑了！谢谢！

提交程序时 @{env} 和 {rid} 应该填啥？
