Tsz Wo (Nicholas), SZE commented on HADOOP-2219:
------------------------------------------------
I am fine with making a new command. However, df in unix is for disk space
usage, not directory space usage. So, it may be confusing. It seems to me
that there is no specific unix command for counting files and directories.
> du like command to count number of files under a given directory

> Key: HADOOP-2219
> URL: https://issues.apache.org/jira/browse/HADOOP-2219
> Project: Hadoop Core
> Issue Type: New Feature
> Components: dfs
> Reporter: Koji Noguchi
> Assignee: Tsz Wo (Nicholas), SZE
>
> To keep the total number of files on dfs low, we like the users to be able to
> easily find out how many files each of their directory contain.
> Currently, we only have fsck or dfs -lsr which takes time.
> Can I ask for an option for du to show the total number of files (as well as
> the total size) of a given directory?
