Some of the previously 2.4 targeted features were made available in 2.3:
- Heterogeneous storage support
- Datanode cache

The following are being targeted for 2.4:
- Use protobuf for fsimge (already in)
- ACLs (in trunk. In a week or so, this will be merged to branch-2.4)
- Rolling upgrades (last bunch of jiras being worked in feature branch.
Will be in 2.4 in around two weeks. Currently testing is in progress)

So HDFS features should be ready in two weeks.
