Subject [jira] [Commented] (HADOOP-10971) Flag to make `hadoop fs -ls` print filenames only
Date Sat, 16 May 2015 15:16:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10971?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14546802#comment-14546802
] 

Akira AJISAKA commented on HADOOP-10971:
----------------------------------------

Thanks [~sekikn] for updating the patch. One comment:
bq. made -C to overrule -u, because timestamp isn't displayed when -C is specified
I don't think -u should be no-op when -C is specified. -u is not only used for displaying
modification time but also used for sorting outputs by modification time when -t is specified
at the same time.

> 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.
