cygwin安装pig遇到如下错误，求大神。

[flyingsky2008]

which: no hadoop in (/cygdrive/d/hadoop/pig-0.12.0-src/bin:/cygdrive/d/Java/jdk1.6.0_10/bin:/usr/local/bin:/usr/bin:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/System32/Wbem:/cygdrive/d/Java/jdk1.6.0_10/jre/bin:/cygdrive/d/Java/jdk1.6.0_10/jre/jre/bin:/cygdrive/c/Program Files/MySQL/MySQL Server 5.0/bin:/usr/bin:/usr/sbin:$PATH:$HADOOP_INSTALL:/cygdirve/d/hadoop/run:/bin:/cygdrive/d/hadoop/pig-0.12.0-src/bin)
cygpath: cannot create short name of D:\hadoop\pig-0.12.0-src\logs
Cannot locate pig-withouthadoop.jar. do 'ant jar-withouthadoop', and try again
其中括号能的部分是我的“PATH”路径；

看起来像是which hadoop 的时候找不到啊。。。。你是不是没有配置hadoop 的shell或者环境变量啊
