Error: java.lang.RuntimeException: PipeMapRed.waitOutputThreads(): subprocess failed with code 127
最近在学大数据来到了MapReduce编程这块- -
用以下这段代码
即使用Hadoop-Streaming运行就tm一直报错
hadoop jar /opt/hadoop-2.7.3/share/hadoop/tools/lib/hadoop-streaming-2.7.3.jar -input /ncdc -output /ncdc_out -mapper max_temp_map.py -reducer max_temp_reduce.py -file max_temp_map.py -file max_temp_reduce.py
Error: java.lang.RuntimeException: PipeMapRed.waitOutputThreads(): subprocess failed with code 127
还剩两个小时我就花了两天时间解决这个问题- -
期间百度了很多地方也Google了很多
方法无非就是CRLF和LF的问题
文件编码的问题，对我来说没用，下面说我的解决方法
解决方法：
LiveDataNode需要大于2，这是我猜的
进入hadoop目录下找到slaves文件
本来我只有一个slave1
加了一个master就好了也就是主机名
下面吐槽一下
真的tm想死 快照删的太快直接打回重装两次 说实话直接裂开
以下是报错信息
各位看看就好
