> 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.
