Haohui Mai commented on HDFS-6994:
----------------------------------
bq. This adds operational complexity for non-Java clients that just want to
integrate with HDFS.
Agree. I think the use case for this library is slightly different than libhdfs
/ libndfs. It is quite beneficial to have a full native client that has zero
dependency on the Java side. One use case is to use the library to verify the
wire compatibility of the HDFS protocols.
Full functional parity is great, but I don't think it should be the main focus
for libhdfs3.

> 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
