Allen Wittenauer commented on HADOOP-2219:
------------------------------------------
The UNIX way of doing that is to use find with a pipe to wc (amongst other
ways). But df -i is probably the closest to a single command.
> 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?
