> HttpFS opens and closes a FileSystem instance against the backend filesystem
> (typically HDFS) on every request. The FileSystem caching is not used as it
> does not have expiration/timeout and filesystem instances in there live
> forever, for long running services like HttpFS this is not a good thing as it
> would keep connections open to the NN.
