hadoop-core-1.0.4-modified.jar

在windows下，使用hadoop-1.0.4自带的hadoop-core-1.0.4.jar时，会抛出权限异常：cause:java.io.IOException: Failed to set permissions of path: \tmp\hadoop-zhuming\mapred\staging\zhumnig-2070047262\.staging to 0700 hadoop-core-1.0.4-modified.jar包，是修改了源码FileUtil.java后，编译得到的hadoop-core-1.0.4-modified.jar。在win平台不会出现权限问题
