Eli Collins commented on HADOOP-6857:
-------------------------------------
I agree with Koji, seeing raw disk space usage should be easy to get from the
CLI, you shouldn't have to enable a quota on a directory to see it, eg see
below that nothing indicates raw disk usage:
{code}
~ $ hadoop fs -mkdir dir
~ $ hadoop fs -put f3mb dir
~ $ hadoop fs -dus dir
hdfs://haus01.sf.cloudera.com:10020/user/eli/dir 3145728
~ $ hadoop fs -count -q dir
none inf none inf 1
1 3145728 hdfs://haus01.sf.cloudera.com:10020/user/eli/dir
{code}
It also sounds like the original issue here was that disk space usage should
not have been added to count if it was already available in dus. Even if we
added raw disk usage to "count", it's wonky that a user can logical disk usage
with "du" but has to switch over to a separate "count" command to get raw disk
usage. Why not make all disk usage available from a single command?
Sound reasonable Nicholas?

> 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
