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?
> RPC support for large data transfers.

> Key: HADOOP-4386
> URL: https://issues.apache.org/jira/browse/HADOOP-4386
> Project: Hadoop Core
> Issue Type: New Feature
> Components: dfs, ipc
> Reporter: Raghu Angadi
>
> 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.
