Ryan Williams commented on HADOOP-10971:
----------------------------------------
Interesting suggestion; if keeping the default and adding the flag allowed for
sooner release, I'd lean towards going that route; it's not that big of a deal
to have different semantics between hadoop- and non-hadoop-{{ls}}.
Also, adding {{-C}} could be viewed as the first step towards a world where
{{-l}} and {{-C}} both exist, in which world the default could be changed less
disruptively, since people would be able to get either format before and after
the incompatible change.
In any case, I'd prefer to focus on the (relatively simpler) {{-C}} addition
here first, but that's just my $0.02.
> Flag to make `hadoop fs -ls` print filenames only

> Key: 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.
