Haohui Mai commented on HDFS-6994:
----------------------------------
bq. I'm very much against boost showing up in Hadoop in any way, shape, or
form. It's always long term pain. I'd much rather take the short term hit of
requiring a modern compiler than deal with boost.
I think this is a fair point. C++11 covers a lot of issues for the original
boost use case. The only remaining gap I see, however, is {{boost::asio}}.
I see a couple possible approaches:
# Wait until C++14 for the networking library.
# Import an WIP implementation for asio in
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3388.pdf
# Use other networking libraries.
I'm a little bit skeptical about (3) because these libraries might not be as
mature and optimized compared to {{boost::asio}}. It might be worthwhile to
take a look at the second approach given the fact that the current code has
been using {{boost::asio}} already.

> 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
> https://github.com/PivotalRD/libhdfs3
