Subject [jira] [Commented] (HDFS-6994) libhdfs3 - A native C/C++ HDFS client
Date Tue, 07 Oct 2014 01:23:34 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14161322#comment-14161322

Colin Patrick McCabe commented on HDFS-6994:
--------------------------------------------

bq. Agree. However, I think when the time of call for merge comes, it requires the reviewers
to look at both sides of the code. Separating it into another branch would make things much
easier and allow ensuring better code quality.

I think there is some misunderstanding here.  There isn't going to be a single "time of merge."
 Zhanwei, Abe and I are fixing up libhdfs3 as we go to have the functionality it needs.  In
other words merging the functionality now, not later.  I'm going to get rid of the code in
hadoop-native-core (I guess I should put up a change for that) since this directory isn't
needed any longer.

> 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
