Robert Chansler updated HADOOP-4008:
------------------------------------
Component/s: dfs
> Make the Client-Datanode streaming protocol concrete
> ----------------------------------------------------
>
> Key: HADOOP-4008
> URL: https://issues.apache.org/jira/browse/HADOOP-4008
> Project: Hadoop Core
> Issue Type: Sub-task
> Components: dfs
> Reporter: Sanjay Radia
>
> The Client-Datanode streaming protocol is a set of message exchanges.
> The messages are not concrete data type s(ie it is not classes or
> interfaces).
> The message exchange could be made concrete by declaring message data types
> and/or interfaces.
> This will help future automated versioning via protocol-buffers style
> approach. It will also help document the interface and can simplify the code.
