> A a library, libhdfs would be better to return errors rather than directly
> exiting. This way the calling application can determine what to do on error.
> And it is more unix library like to handle errors this way.
> Some applications like fuse-dfs need to handle the exit themselves after
> emitting an appropriate error message to its log.
