>
> 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.
