> the changes for the hdfs client classpath make instantiating {{HdfsConfiguration}} from the client impossible; it only lives server side. This breaks any app which creates one.
> I know people will look at the {{@Private}} tag and say "don't do that then", but it's worth considering precisely why I, at least, do this: it's the only way to guarantee that the hdfs-default and hdfs-site resources get on the classpath, including all the security settings. It's precisely the use case which {{HdfsConfigurationLoader.init();}} offers internally to the hdfs code.
> What am I meant to do now?
