If you just want to test Hadoop on Windows the actual permissions are not that
important. I updated RawLocalFileSystem.java so it just assigns some generous
value to all files everytime ignoring the actual value in the 'permission'
argument.
/**
* Use the command chmod to set permission.
*/
@Override
public void setPermission (Path p, FsPermission permission) throws IOException
{
//FileUtil.setPermission (pathToFile (p), permission);
FileUtil.setPermission (pathToFile (p), permission777);
}
private FsPermission permission777 = FsPermission.valueOf ("-rwxrwxrwx");
Then rebuild Hadoop using a command like:
ant -l build.log -Dtest.output=yes test-contrib
See: http://wiki.apache.org/hadoop/FAQ#Building_.2BAC8_Testing_Hadoop_on_Windows
Replace the hadoop-core*.jar under 'share/hadoop' with
hadoop-core*.SNAPSHOT.jar
created under 'build'
