Subject [jira] [Commented] (HADOOP-7341) Fix option parsing in CommandFormat
Date Tue, 31 May 2011 18:59:51 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7341?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13041752#comment-13041752

Daryn Sharp commented on HADOOP-7341:
-------------------------------------

Aaron:
I completely agree the parser needs to be changed, but I don't currently have the time available.
 My goal here is a very small/quick change to revert how every FsShell command (except count)
to how it used to work.  If you're ok with that, I think another jira should switch the parser.

Todd:
I suppose it comes down to whether hadoop should favor posix or gnu extensions?

{noformat}
$ mkdir a b

$ ls a -l b
a:
total 0
b:
total 0

$ POSIXLY_CORRECT=1 ls a -l b
ls: -l: No such file or directory
a:
b:
{noformat}

I was just planning to restore the prior behavior.

> CommandFormat currently allows options in any location within the args.  This is not
the intended behavior for FsShell commands.  Prior to the redesign, the commands used to expect
option processing to stop at the first non-option.
> CommandFormat was an existing class prior the redesign, but it was only used by "count"
to find the -q flag.  All commands were converted to using this class, thus inherited the
unintended behavior.
