Sam Steingold created HADOOP-10724:
--------------------------------------
Summary: `hadoop fs -du -h` incorrectly formatted
Key: HADOOP-10724
URL: https://issues.apache.org/jira/browse/HADOOP-10724
Project: Hadoop Common
Issue Type: Bug
Components: fs
Reporter: Sam Steingold
{{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) "
