Suresh Srinivas commented on HDFS-2656:
---------------------------------------
bq. I'm also a little surprised this was checked in w/o it actually building
(HDFS-3909).
It is not built by Jenkins because of a need for a library. It has been
manually tested as you see in various benchmarks etc. posted.

> 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.
