Subject [jira] [Commented] (HADOOP-10388) Pure native hadoop client
Date Sun, 09 Mar 2014 12:05:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10388?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13925187#comment-13925187
] 

Binglin Chang commented on HADOOP-10388:
----------------------------------------

Although c is viable, I would suggest using c++11, that will help us get rid of lot of dependencies
and make the code smaller.
I was writing a client just for fun, it uses c++11, depends on protobuf, json-c, sasl2, gtest
and cmake, about 8k LOC. It is on github now: https://github.com/decster/libhadoopclient.
Hope some of the code can be useful here.

> A pure native hadoop client has following use case/advantages:
> 1.  writing Yarn applications using c++
> 2.  direct access to HDFS, without extra proxy overhead, comparing to web/nfs interface.
> 3.  wrap native library to support more languages, e.g. python
> 4.  lightweight, small footprint compare to several hundred MB of JDK and hadoop library
with various dependencies.
