Hairong Kuang commented on HADOOP-771:
--------------------------------------
Currently FileSystem APIs only support "rmr". To avoid programmatic error,
should we change the FileSystem interface so that it distinguishes between rm
and rmr? Instead of having "void delete(Path)", we could have "void
delete(Path, boolean)". The boolean flag indicates if the deletion is recursive
or not.
> 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().
