Ankur commented on HADOOP-4386:
-------------------------------

Is anyone working on this? if yes then are we going ahead with the approach of modifying hadoop
RPC and add async method to the protocol as Doug described on  HADOOP-3856?

> Currently HDFS has a socket level protocol for serving HDFS data to clients. Clients
do not use RPCs to read or write data. Fundamentally there is no reason why this data transfer
 can not use RPCs.
> This jira is place holder for any porting Datanode transfers to RPC. This topic has been
discussed in varying detail many times, the latest being in the context of HADOOP-3856. There
are quite a few issues to be resolved both at API level and at implementation level. 
> We should probably copy some of the comments from HADOOP-3856 to here.
