Subject [jira] Commented: (HADOOP-559) Support file patterns in dfs commands
Date Tue, 26 Sep 2006 19:55:51 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-559?page=comments#action_12437926 ] 
Doug Cutting commented on HADOOP-559:

> there is a bug in ListPathsRaw of LocalFileSystem

Can we fix that in this patch too?

> DFSShell uses listPaths[] of FileSystem. So I make the method public.

I'm okay with this, but a better javadoc would be nice.


> Support file patterns in dfs commands

>                 Key: HADOOP-559
>                 URL: http://issues.apache.org/jira/browse/HADOOP-559
>             Project: Hadoop
>          Issue Type: New Feature
>          Components: dfs
>    Affects Versions: 0.6.2
>            Reporter: Hairong Kuang
>         Assigned To: Hairong Kuang
>             Fix For: 0.7.0
>         Attachments: glob.patch, glob.patch
> Currently DFSShell does not support file patterns in dfs file names. It's quite inconvenient
for users when they need to manipulate multiple files.
> This issue is intended to extend DFSShell to interprete file patterns. A file pattern
contains special special pattern matching characters:
> ?: matches any character
> *: matches zero or more characters
> [abc]: matches a character from character set {a, b, c}
> [a-c]: matches a character from character range: {a...c}
> [^a]: matches a character not in character set or range {a}
> \c:  escape any special meaning of character c
