Cygwin运行nutch报错：Failed to set permissions of path
?
官方BUG参考：
https://issues.apache.org/jira/browse/HADOOP-7682
?
解决方法：
1、下载并解压http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-1.1.2/hadoop-1.1.2.tar.gz
2、修改hadoop-1.1.2\src\core\org\apache\hadoop\fs\FileUtil.java，搜索 Failed to set permissions of path，找到689行，把throw new IOException改为LOG.warn
3、修改hadoop-1.1.2\build.xml，搜索autoreconf，移除匹配的6个executable="autoreconf"的exec配置
4、下载解压ant，将ant目录下的bin目录加入环境变量path
5、在命令行切换到hadoop-1.1.2目录，执行ant
6、用新生成的hadoop-1.1.2\build\hadoop-core-1.1.3-SNAPSHOT.jar替换nutch的hadoop-core-1.0.3.jar
