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
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
