I agree. Why don't you guys separate this into a few subtasks, and use the
HADOOP-10388 branch as the target?
bq. Personally I think that this is an alternative implementation of libhdfs. I
don't think we need to get rid of boost for now, but I think the code can be
put in the contrib directory which is not built by default, but still allow
other people to check it out if they're interested.
I think we should make this useful to as many people as possible. That's the
reason I made my comment about the possible boost dependency issue. I looked
at this a little more closely, though, and I see that the purpose of boost is
to substitute for C\+\+11 features such as {{std::thread}}, in cases where the
compiler is too old to provide them. With that in mind, I think that it's ok
for now. I do think we should do the Jenkins build without boost, to make sure
that the C\+\+11 code works. C\+\+11 is clearly the future for C++ and we
should be prepared for it.
I want to reiterate that we should have a way to switch between this new
library and the existing libhdfs. I'd be happy to work on that (I can
re-purpose the existing code from HADOOP-10388 to do that) and it will expand
the user-base big-time.

> Hi All
> I just got the permission to open source libhdfs3, which is a native C/C++
> HDFS client based on Hadoop RPC protocol and HDFS Data Transfer Protocol.
> libhdfs3 provide the libhdfs style C interface and a C++ interface. Support
> both HADOOP RPC version 8 and 9. Support Namenode HA and Kerberos
> authentication.
> libhdfs3 is currently used by HAWQ of Pivotal
> I'd like to integrate libhdfs3 into HDFS source code to benefit others.
> You can find libhdfs3 code from github
