Suresh Srinivas commented on HDFS-1475: --------------------------------------- +1 for the patch. Will commit this after HADOOP-7378. > 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.) -- This message is automatically generated by JIRA.
