• Type: Bug

Description

hadoop fs -du -h prints sizes with a space between the number and the unit:

$ hadoop fs -du -h ..... 
91.7 G   ....
583.1 M  ....
97.6 K   .....

The standard unix du -h does not:

$ du -h
400K    ...
404K    ....
480K    .....

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: "-h --human-numeric-sort
  compare human readable numbers (e.g., 2K 1G) "
• du: "-h, --human-readable
  print sizes in human readable format (e.g., 1K 234M 2G) "
