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-Administrator\mapred\staging\Administrator-519341271\.staging to 0700 上述jar包，是修改了源码FileUtil.java后，编译得到的hadoop-core-1.

解决windows下远程调试hadoop权限问题（ ERROR security.UserGroupInformation: PriviledgedActionException as:Administrator cause:java.io.IOException: Failed to set permissions of path:）重新编译了hadoop-core-1.2.1,注释了包中org.apache.hadoop.fs下FileUtil.class中的checkReturnValu

编译过的hadoop-core-1.0.4.jar，可以在本地模拟MapReduce 如果Eclipse workspace在d:，则我们可以把d:的某个目录，比如d:\input作为输入目录；d:\output作为输出目录。 MapReduce编程模型里面这样写就可以了： FileInputFormat.setInputPaths(job, new Path("/input")); FileOutputFormat.setOutputPath(job, new Path("/output")
修改过的注释掉checkReturnValue方法后hadoop-core-1.2.0的hadoop-core-1.2.0.jar包，另有FileUtil.java编译后的class文件，可用于替换掉hadoop-core-1.2.0.jar中对应的编译类 解决hadoop运行在windows下的错误Exception in thread "main" java.io.IOException: Failed to set permissions of path: \tmp\hadoop-Adm
eclipse远程调试hadoop时 报出eclipse Hadoop Failed to set permissions of path错误 修改hadoop core包中FileUtil java文件 里面有checkReturnValue方法 将代码throw new IOException "Failed to set permissions of path: ;为改为LOG warn 重新打包后替换原来的jar包 即可;本资源的jar包为修改后的jar包 可直接利用 "&g
解决nutch 1.9在cgywin中运行报Injector: java.io.IOException: Failed to set permissions of path: \tmp\hadoop-Administrator\mapred\staging\Administrator139727905\.staging to 0700错误的问题，即修改hadoop-core-1.2.0.jar中FileUtil.java类中checkReturnValue方法后jar包
