[jira] [Created] (HADOOP-10971) Flag to make `hadoop fs -ls` print filenames only

Ryan Williams created HADOOP-10971:
--------------------------------------

             Summary: Flag to make `hadoop fs -ls` print filenames only
                 Key: HADOOP-10971
                 URL: https://issues.apache.org/jira/browse/HADOOP-10971
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs
    Affects Versions: 2.3.0
            Reporter: Ryan Williams


It would be useful to have a flag that made {{hadoop fs -ls}} only print filenames, instead of full {{stat}} info. The "{{-C}}" flag from GNU {{ls}} is the closest analog to this behavior that I've found, so I propose that as the flag.

Per [this stackoverflow answer|http://stackoverflow.com/a/21574829], I've reluctantly added a {{hadoop-ls-C}} wrapper that expands to {{hadoop fs -ls "$@" | sed 1d | perl -wlne'print +(split " ",$_,8)\[7\]'}} to a few projects I've worked on, and it would obviously be nice to have hadoop save me (and others) from such hackery.
