Rodrigo Schmidt commented on HADOOP-6690:
-----------------------------------------

I noticed the problem when using contrib/raid, which currently relies on FilterFileSystem (because it was originally implemented on hadoop 0.20). Maybe we should change the trunk version to work with FilterFs.

However, this workaround doesn't make FilterFileSystem more correct. We should either fix it or deprecate it so that people don't feel compelled to use it in the future. What do you think?

> FilterFileSystem seems to be a little outdated and it doesn't implement a few methods (setTimes being the most important one):
> - setTimes(Path, long, long)
> - copyFromLocalFile(boolean,boolean, Path, Path)
> - copyFromLocalFile(boolean, boolean, Path[], Path)
> - getUsed()
> - deleteOnExit()
> I'm not sure if all of these methods should be wrapped in FilterFileSystem, but given its purpose, I would say the more the better. It would be great to have other people's opinions about this.
