Hadoop streaming mapreduce未运行

我已经从下载了Hadoop2.6.0和HadoopStreaming（因为我没有空间运行CDH或Sandbox）

我指挥

bin/hadoop jar contrib/hadoop-streaming-2.6.0.jar \
-file ${HADOOP_HOME}/py_mapred/mapper.py -mapper ${HADOOP_HOME}/py_mapred/mapper.py \
-file ${HADOOP_HOME}/py_mapred/reducer.py -reducer ${HADOOP_HOME}/py_mapred/reducer.py \
-input /input/davinci/* -output /input/davinci-output

我将下载的流媒体jar存储在${HADOOP_HOME}/contrib中，其他文件存储在py_mapred中。同时，我将从本地复制到hdfs上的/input目录。现在，当我运行该命令时，将显示以下行：

15/08/14 17:35:45 WARN streaming.StreamJob: -file option is deprecated, please use generic option -files instead.

看起来该命令已被接受。我检查了localhost:8088，作业确实注册了。但是它没有运行，尽管它说的是

正在运行job:job\u 14395388212023\u 0002

。我的命令有什么问题吗？这是由于权限设置造成的吗？为什么作业没有运行

谢谢

以下是流媒体的正确方式：

bin/hadoop jar contrib/hadoop-streaming-2.6.0.jar \
-file ${HADOOP_HOME}/py_mapred/mapper.py -mapper '/usr/bin/python mapper.py' -file ${HADOOP_HOME}/py_mapred/reducer.py -reducer '/usr/bin/python reducer.py' -input /input/davinci/* -output /input/davinci-output

我也遇到过类似的问题。
