Stephen G Ahlgren commented on HDFS-6994:
-----------------------------------------

Thank you for the note Zhanwei.  I've become familiar with libhdfs3 on Linux and would like to check in with you about your thoughts for two branches (hadoop hdfs-6994 branch v. the pivotal apache-rpc-9 branch) before committing any changes.

There are Windows-specific changes in the hdfs-6994 branch that aren't reflected in the pivotal code and namespace/method naming changes between the two as well.  Should we try and reconcile the two branches or focus efforts on the pivotal apache-rpc-9 branch, moving Windows-specific code in as needed from elsewhere?

Thank you kindly in advance, I just want to make sure we're on the same page before trundling forward.

Best,
Steve A.

> 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/Pivotal-Data-Attic/pivotalrd-libhdfs3
