Colin Patrick McCabe commented on HADOOP-10388:
-----------------------------------------------
This seems like a good idea. I would add another advantage to the list: a C or
C++ library could make it easier to debug crashes than a JNI one.
One issue here is that we could be talking about a lot of code here. I think
we should decide on a coding style to use so that everyone can contribute and
understand the code that others have written. If C++, I would suggest the
Google C++ style guide. See
http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml
Pure C is also a viable choice, in which case I would recommend something more
like the Linux kernel style guide (but with 4-space indent)

> Key: HADOOP-10388
> URL: https://issues.apache.org/jira/browse/HADOOP-10388
> Project: Hadoop Common
> Issue Type: New Feature
> Reporter: Binglin Chang
>
> 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.
