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: 0.20.1 Environment: any Reporter: Greg Connor Priority: Minor 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.) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
