[jira] [Commented] (MAPREDUCE-2707) ProtoOverHadoopRpcEngine without using TunnelProtocol over WritableRpc

["Jitendra Nath Pandey (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2707?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13067319#comment-13067319 ] 

Jitendra Nath Pandey commented on MAPREDUCE-2707:
-------------------------------------------------

 This jira doesn't intend to remove writable from ipc.Client/Server. That is proposed in a different jira (HADOOP-7399). This will just remove TunnelProtocol but the protocol buffer messages will still be wrapped in a generic Writable and passed to ipc Client. 
  When HADOOP-7399 is ready to go, ProtoOverHadoopRpcEngine will be modified not to wrap request/response into Writable.

> ProtoOverHadoopRpcEngine is introduced in MR-279, which uses TunnelProtocol over WritableRpcEngine. This jira removes the tunnel protocol and lets ProtoOverHadoopRpcEngine directly interact with ipc.Client and ipc.Server.
