Steve Loughran commented on HADOOP-10388:
-----------------------------------------
# +1 to avoid leading edge features that need practical experience in writing
modern C++ code to make use of. Some of us committers may have C/C++ skills,
but they'll not be current.
# I'd like it to build on OS/X so that mac builds catch regressions, even if
isn't for production.
# I'm not up to date with C++ test frameworks; xUnit code always played up in
the past (2003) as tests weren't independent enough, and resource leakage never
got picked up. Something good that Jenkins could run against MiniDFS and
MiniYARN clusters would be nice.
bq. c++ does not have good binary compatibility(mainly virtual method) issue,
so we need to be careful.
Assume destination-side build, source RPMs & debs with specific version
binaries produced by downstream packagers. Windows builds -which we should also
support if possible- will need locking down by the windows developer groups.
That is "no guarantee of binary compatibility across versions for now"

> 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.
