------------------------------------------

Given the discussion on HIVE-3098, can we take this JIRA out of the parking lot?

> 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.
