hi,all:
As we known , now hadoop can't run on windows because of the unix shell
used by ant and DF utility used by DF.java ,I think the unix shell could be
easyly replace with java code or ant script ,And in Java 6, I find the DF
utility can be replace with getUsableSpace()and getTotalSpace() of
java.io.File. Between the two, you can show how much space
each file system has available and has in total(See the code listed below). May
be the DF class should made to more smart to support different OS and JDK .
---------------------------
public class Space{
public static void main(String args[]){
Console console=System.console();
File roots[]=File.listRoots();
for(File root : roots){
console.printf("%s has %,d of %,d free%n", root.getPath(),
root.getUsableSpace(), root.getTotalSpace()
);
}
}
}
---------------------------
