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) "
