Mahadev konar updated HADOOP-771:
---------------------------------
Attachment: patch_771_1.patch
this patch create a new filesystem api delte(path, boolean) which would throw
an exception in case path is a directory, is non emppty and boolean is false.
If boolean is set to true it behaves the same as previous delete. I have also
deprecated delete(path). applications would use delete(path, boolean) instead.
I have made changes to all the other file systems to implement them correctly.
> Namenode should return error when trying to delete non-empty directory

> Currently, the namenode.delete() method allows recursive deletion of a
> directory. That is, even a non-empty directory could be deleted using
> namenode.delete(). To avoid costly programmer errors, the namenode should not
> remove the non-empty directories in this method. Recursively deleting
> directory should either be performed with listPaths() followed by a delete()
> for every path, or with a specific namenode method such as deleteRecursive().
