Description

Here's a jira to track deprecating FileSystem. There are two high-level tasks:

1. Moving clients in common and mapreduce onto FileContext. I think this is currently blocked on HADOOP-6356 and HADOOP-6361. Anything else preventing them from being moved over? Any clients we could move over today?

2. Moving file system implementations onto AbstractFileSystem. Currently Hdfs and FilterFS (and local and checksum) extend AFS. RawLocalFileSystem uses the delegator. S3, ftp and others need to be moved over. Don't think there's anything blocking this stuff.

3. Stabilize FileContext
