1762) (out= 749)(deflated 57%)
adding: mypackage/WordCount1$TokenizerMapper.class(in = 1759) (out= 762)(deflated 56%)
adding: log4j.properties(in = 476) (out= 172)(deflated 63%)
虽然有warning，但是不影响结果。编译后，我们来简单的测试一下。
先生成测试数据：while true; do seq 1 100000 >> tmpfile; done; 差不多可以了就Ctrl+c
然后将数据放到hdfs上，hadoop fs -put tmpfile /data/
接着运行MapReduce程序：hadoop jar WordCount.jar mypackage/WordCount1 /data/tmpfile /output2
效果如下：
