Colin Patrick McCabe commented on HADOOP-10388:
-----------------------------------------------
C++ is viable, but we need to remember that C+\+11 is not a coding standard.
We need to adopt a coding standard such as the Google Coding Standard and
follow it closely for C+\+ to be a practical choice.
I also think we should be able to compile this code on Red Hat 6, since that's
the platform that a lot of our users are using (actually, some of our users are
using RHEL5, but I think we can safely assume that the sun will set on that one
before this is ready.) This means certain bleeding-edge C+\+ features will be
unavailable. But on the plus side, we won't use language features that later
turn out to be problematic (it's nice not being an early adopter sometimes.)
I also wrote some C++ code in this direction a while ago. I never finished it,
though. I'll see if I can dig it up.
> Pure native hadoop client
> -------------------------
>
> 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.
