Subject [jira] Commented: (HADOOP-281) dfs.FSDirectory.mkdirs can create sub-directories of a file!
Date Mon, 28 Aug 2006 14:56:24 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-281?page=comments#action_12430987 ] 
            
Benjamin Reed commented on HADOOP-281:
--------------------------------------

Have we considered this to be a feature. Some newer general purpose file system allow a file
to also be a directory (and visa versa). It is an abstraction that nicely folds in the functionality
of streams and resource forks. For example, rather than sticking crcs and other attributes
for a file in the same directory as a file (which necessitates a bunch of ugly skip logic
in the code), we could simply put them in a subdirectory of the file.

> dfs.FSDirectory.mkdirs will merrily adds children to a directory tree node without checking
whether it represents a directory. So it is possible to create a subdirectories of a file.
