我试图找到解决斯坦福的cs246 2014硬件解决方案的最受欢迎的家伙在校园里。
我不断遇到错误“error:java.lang.runtimeexception:pipemapred.waitoutputthreads（）：subprocess failed with code 1”
我的mapper的python代码是

{#!/usr/bin/python
import sys
ID = None
fcount = 0
count = 0
for line in sys.stdin:
    line = line.strip()
    words = line.split("        ")
    ID,friends = words
    fcount = len(friends.split(","))
    #count = fcount * -1
# for i in friends:
# if i != ','
# fcount +=1
    print "%d\t%s" %(fcount,ID)
}

我的代码是
{

# !/usr/bin/python
import sys
ID = None
fcount = 0
count = 0
for line in sys.stdin:
    line = line.strip()
    words = line.split("        ")
    ID,friends = words
    fcount = len(friends.split(","))
    #count = fcount * -1
# for i in friends:
# if i != ','
# fcount +=1
    print "%d\t%s" %(fcount,ID)

}
任何帮助都将不胜感激
