Koji Noguchi commented on HADOOP-6857:
--------------------------------------
A little confused. I thought "fs -count" shows hdfs usage same as "fs -du" at
the thrid column.
{noformat}
[knoguchi ~]$ hadoop dfs -dus /user/knoguchi
hdfs://abc-nn1.com/user/knoguchi 2603203340273
[knoguchi ~]$ hadoop dfs -count /user/knoguchi
1580 20624 2603203340273 hdfs://abc-nn1.com/user/knoguchi
[knoguchi ~]$
{noformat}
If quota is enabled on that dir and "-q" is passed, it would show the remaining
raw space available.
{noformat}
[knoguchi ~]$ hadoop dfs -count -q /user/knoguchi
50000 27796 13194139533312 5384528402193 1580

You can get the raw space usage then. (quota - raw\_remaining).
However *this is only if you have quota enabled on that particular dir*.

> Currently FsShell report HDFS usage with "hadoop fs -dus <path>" command.
> Since replication level is per file level, it would be nice to add raw disk
> usage including the replication factor (maybe "hadoop fs -dus -raw <path>"?).
> This will allow to assess resource usage more accurately. -- Alex K
