我有一个macbook pro＆amp;我已经在它上面安装了hadoop 2.7.3： https://www.youtube.com/watch?v=06hpB_Rfv-w
我正在尝试通过python3＆amp;运行hadoop MRJob命令它给了我这个错误：。

问题是如果我用python2.7运行相同的命令，那么它运行正常＆amp;告诉我正确的输出。

这是我的MR_Jobs.py：
from mrjob.job import MRJob
import re
WORD_RE = re.compile(r"[\w']+")
class MRWordFreqCount(MRJob):
def mapper(self, _, line):
for word in WORD_RE.findall(line):
yield (word.lower(), 1)
def combiner(self, word, counts):
yield (word, sum(counts))
def reducer(self, word, counts):
yield (word, sum(counts))
if __name__ == '__main__':
MRWordFreqCount.run()
＆安培;＆安培;
我使用此命令在hadoop上运行它：
python3 /Users/bhoots21304/PycharmProjects/untitled/MRJobs/Mr_Jobs.py -r hadoop /Users/bhoots21304/PycharmProjects/untitled/MRJobs/File.txt
如果我在我的ubuntu机器上使用上面提到的命令运行相同的文件..但是当我在我的mac机器上运行相同的东西时它会给我一个错误。
以下是我的mac机器的日志：

只需使用以下内容创建~/.mrjob.conf文件：
runners:
hadoop:
python_bin: /usr/local/bin/python3
hadoop_bin: /usr/local/opt/hadoop/bin/hadoop
hadoop_streaming_jar: /usr/local/opt/hadoop/libexec/share/hadoop/tools/lib/hadoop-streaming-*.jar
然后使用以下命令运行程序：
python3 your_program.py -r hadoop input.txt
