Under Windows: Failed to set permissions of the path: \tmp\ \.staging to 0700

This official bug has been encountered before ............. But.......

==================================================

12/04/24 15:32:44 WARN util. nativecodeloader:unable to load Native-hadoop library for your platform ... using Builtin-java classes where applicable

==========================================================================

This is the Windows file permissions issue, under Linux can run normally, there is no such a problem.

The workaround is to modify the/hadoop-1.0.2/src/core/org/apache/hadoop/fs/ Fileutil.java inside the Checkreturnvalue, commented out can (some rough, under the window, can not check)

......    private static void Checkreturnvalue (Boolean rv, File p,                                         fspermission permission                                         ) throws IOException {      /** i F (!RV) {throw new IOException ("Failed to set permissions of path:" + P + "to" + String.Format ("%04o", Permission.tosh ORT ())); } **/    }  

recompile the package Hadoop-core-1.0.2.jar, replacing the Hadoop-core-1.0.2.jar in the hadoop-1.0.2 root directory.

You can also copy the source of the ORG.APACHE.HADOOP.FS package to the project, and then modify the Fileutil.java in the Checkreturnvalue method to comment out the contents of the content can be

After replacing, refresh the project, set the correct jar dependency, and run Wordcounttest now.

Official Bug Reference:

https://issues.apache.org/jira/browse/HADOOP-7682

Workaround:

1. Download and unzip http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-1.1.2/hadoop-1.1.2.tar.gz

2. Modify Hadoop-1.1.2\src\core\org\apache\hadoop\fs\fileutil.java, search Failed to set permissions of path, find 689 rows, throw new IOException Change to Log.warn

3, modify Hadoop-1.1.2\build.xml, search autoreconf, remove the matching 6 executable= "autoreconf" exec Configuration

4. Download and extract ant, add the bin directory under the Ant directory to the environment variable path

5. Switch to the hadoop-1.1.2 directory at the command line and execute the ant

6. Replace the Hadoop-core-1.0.3.jar with the newly generated Hadoop-1.1.2\build\hadoop-core-1.1.3-snapshot.jar
