---------------------------------------

Hi all

I have open sourced the libhdfs3, which is a native C/C++ client developed by Pivotal and
used in HAWQ. See HDFS-6994

> 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.
