Eli Collins updated HDFS-2656:
------------------------------

    Fix Version/s:     (was: 3.0.0)
                   2.0.3-alpha

Updating the fix version to 2.0.3 since it looks like Nicholas merged this?

> 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.
