【MapReduce】Streaming Job Failed!

在尝试运行一个使用Python编写的MapReduce程序时,在Hadoop环境中遇到错误。经过检查,发现错误可能源于MR脚本、环境配置或jar包问题。最终通过查找正确的hadoop-streaming.jar位置并更新jar包解决了问题。经验总结指出,ClassNotFound异常可能是jar包与环境不匹配,且查看运行日志对于定位问题至关重要。

报错发生情况:

用Python写好了一个MR程序,使用Linux环境本地测试正常。
在Hadoop环境上测试就报错。

我的环境:

$hadoop version
Hadoop 2.5.2
...

执行指令:

hadoop jar $HADOOP_INSTALL_HOME/contrib/streaming/hadoop-*streaming*.jar   \
-file ./mapper.py -mapper ./mapper.py \
-file ./reducer.py -reducer ./reducer.py \
-input /data/poem/data_test \
-output /data/poem/result
