Sanjay Radia commented on HDFS-2246:
------------------------------------
HDFS-347 discusses ways to optimize reads for local clients. A clean design is
fairly involved. A shortcut has been proposed
where the client access the hdfs file blocks directly; this works if the client
is the same user/group as the DN daemon.
This is non-invasive and is a good short term solution till HDFS-347 is
completed.
