> In discussion during MAPREDUCE-5508, we realized that any {{FileSystem}} subclass must implement an idempotent {{close}} method, due to potential multi-threaded interactions with the {{FileSystem#Cache}}.  We should state this in the JavaDoc for {{FileSystem#close}}, so that subclass implementers are aware.
