Andrew Wang updated HADOOP-10724:
---------------------------------
    Target Version/s:   (was: 3.0.0)

Dropping 3.0.0 target version since this is an incompatible change and beta1 is up, this will have to wait for the next major release.

> {{hadoop fs -du -h}} prints sizes with a space between the number and the unit:
> {code}
> $ hadoop fs -du -h ..... 
> 91.7 G   ....
> 583.1 M  ....
> 97.6 K   .....
> {code}
> The standard unix {{du -h}} does not:
> {code}
> $ du -h
> 400K    ...
> 404K    ....
> 480K    .....
> {code}
> the result is that the output of {{du -h}} is properly sorted by {{sort -h}} while the output of {{hadoop fs -du -h}} is *not* properly sorted by it.
> Please see 
> * [sort|http://linux.die.net/man/1/sort]: "-h --human-numeric-sort
>     compare human readable numbers (e.g., 2K 1G) "
> * [du|http://linux.die.net/man/1/du]: "-h, --human-readable
>     print sizes in human readable format (e.g., 1K 234M 2G) "
