Subject [jira] Updated: (HADOOP-6422) permit RPC protocols to be implemented by Avro
Date Sat, 12 Dec 2009 01:13:18 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-6422?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Doug Cutting updated HADOOP-6422:
---------------------------------

    Attachment: HADOOP-6422.patch

Here's a new version that:
  - renames AvroRpc to AvroRpcEngine
  - changes a Class to Class<?> to avoid requiring an @Suppress("unchecked").

When I actually commit this, I'll use 'svn cp' so that WritableRpcEngine and AvroRpcEngine
have history from RPC.java and AvroRpc respectively.

> To more easily permit Hadoop to evolve to use Avro RPC, I propose to change RPC to use
different implementations for clients and servers based on the configuration.  This is not
intended as an end-user configuration: only a single RPC implementation will be supported
in a given release, but rather a tool to permit us to more easily develop and test new RPC
implementations.  As such, the configuration parameters used would not be documented.
