> Want a -d flag in hadoop dfs -ls : Do not expand directories
> ------------------------------------------------------------
>
> Key: HDFS-1475
> URL: https://issues.apache.org/jira/browse/HDFS-1475
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs client
> Affects Versions: 0.23.0
> Environment: any
> Reporter: Greg Connor
> Assignee: Daryn Sharp
> Priority: Minor
> Attachments: HDFS-1475-2.patch, HDFS-1475.patch
>
>
> I would really love it if dfs -ls had a -d flag, like unix ls -d, which would
> list the directories matching the name or pattern but *not* their contents.
> Current behavior is to expand every matching dir and list its contents, which
> is awkward if I just want to see the matching dirs themselves (and their
> permissions). Worse, if a directory exists but is empty, -ls simply returns
> no output at all, which is unhelpful.
> So far we have used some ugly workarounds to this in various scripts, such as
> -ls /path/to |grep dir # wasteful, and problematic if "dir" is a
> substring of the path
> -stat /path/to/dir "Exists" # stat has no way to get back the full path,
> sadly
> -count /path/to/dir # works but is probably overkill.
> Really there is no reliable replacement for ls -d -- the above hacks will
> work but only for certain isolated contexts. (I'm not a java programmer, or
> else I would probably submit a patch for this, or make my own jar file to do
> this since I need it a lot.)
