Colin Patrick McCabe commented on HADOOP-10388:
-----------------------------------------------
I was going to post an RPC client using libuv. libuv is nice because it's
cross-platform (including UNIX and Windows), MIT-licensed, and has platform
wrapper functions like uv_thread_create and uv_mutex_lock, etc. so we won't
have to write our own platform stuff for Linux, Windows, etc. libuv also
supports async (TCP) I/O, which I would like to have in the RPC client to
provide flexibility.
I think the best structure is to start with the RPC library in hadoop-common,
and then perhaps work on a native HDFS client that uses it in hadoop-hdfs.
There will be a lot to do there and we can split up the work. I'm going to try
to post something for RPC by next week.

> Project: Hadoop Common
> Issue Type: New Feature
> Reporter: Binglin Chang
> Assignee: Colin Patrick McCabe
>
> A pure native hadoop client has following use case/advantages:
> 1. writing Yarn applications using c++
> 2. direct access to HDFS, without extra proxy overhead, comparing to web/nfs
> interface.
> 3. wrap native library to support more languages, e.g. python
> 4. lightweight, small footprint compare to several hundred MB of JDK and
> hadoop library with various dependencies.
