Jing Zhao commented on HDFS-2656:
---------------------------------

And for the name, because the patch is still at an early stage, we currently 
call it "libhdfs2" to distinguish with libhdfs. We may decide its name later.

> Currently, the implementation of libhdfs is based on JNI. The overhead of JVM 
> seems a little big, and libhdfs can also not be used in the environment 
> without hdfs.
> It seems a good idea to implement a pure c client by wrapping webhdfs. It 
> also can be used to access different version of hdfs.
