I agree that HDFS-2246 is a short term solution and we should not keep it there forever. 
However, we still need a transition period to replace an old mechanism by a new one.  No?

Because it doesn't make sense to support multiple mechanisms for the
same thing.

2246 was always intended to be a *short term solution* util 347 was
completed, eg see Sanjay's first comment on 2246:   "A shortcut has
been proposed where the client access the hdfs file blocks directly...
This is non-invasive and is a good short term solution till HDFS-347
is completed."
