Doug Cutting commented on HADOOP-6223:
--------------------------------------
> AFS impls all end with fs
I'd generally prefer "Fs".
When acronyms are incorporated in Java names there are two styles: all caps or
capitalized. I prefer capitalized (e.g., FooUrl versus FooURL). I have also
seen this recommended in several Java style guides and never the contrary, e.g.:

http://stackoverflow.com/questions/1176950/acronyms-in-camel-back/1177184
etc.
FTP is an independent acronym, so FtpFs is probably best.
HD and K are not independent acronyms, so "Hdfs" and "Kfs" are probably
preferred.
The rest are simpler: FilterFs, LocalFs, RawLocalFs, S3Fs, & S3NativeFs.

> The FileContext API (HADOOP-4952) provides an improved interface for the
> application writer.
> This lets us simplify the FileSystem API since it will no longer need to deal
> with notions of default filesystem [ / ], wd, and config
> defaults for blocksize, replication factor etc. Further it will not need the
> many overloaded methods for create() and open() since
> the FileContext API provides that convenience.
> The FileSystem API can be simplified and can now be restricted to those
> implementing new file systems.
> This jira proposes that we create new file system API, and deprecate
> FileSystem API after a few releases.
