Attachment: HDFS-7866.4.patch
The v4 patch is mainly for review and testing. It basically includes:
1. Add a new system EC policy {{RS-3-2}} and set it as the default policy. The
3-2 schema is nothing specific and just for testing. And we can revert to our
current default policy (or make it configurable) when the patch is ready.
2. EC policy can be retrieved either by name or by ID. The ID is stored in
HEADER::replication in InodeFile, as suggested by the TODO comment.
3. Lots of modifications to the tests to make them work with multiple policies.
This may better fit as a follow-on task. But to verify the patch I have to make
the tests pass here.
