Subject [jira] Created: (HADOOP-4386) RPC support for large data transfers.
Date Thu, 09 Oct 2008 21:50:44 GMT
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.
