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.
