Subject [jira] Commented: (HADOOP-423) file paths are not normalized
Date Thu, 21 Sep 2006 22:18:24 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-423?page=comments#action_12436672 ] 
Doug Cutting commented on HADOOP-423:

I think, as a safeguard, we should probably also disallow "." and ".." as file or directory

these names.

While we're at it, should we also prohibit "/" and ":" in names?  I think so.  Currently it
is impossible to create a Path with a slash in a name, although colons are permitted.

> Paths containing  '.' or '..' are not normalized -- the corresponding directories actually
seem to be created. This is inconsistent and unexpected behavior, and  is particularly painful
when running from a working directory, using relative paths that start with ...
