>
> When DistributedRaidFileSystem.close() is called, it does not remove itself
> from the FileSystem cache, but it does close the underlying filesystem, e.g.
> DFS.
> Because the DRFS with the closed DFS is still in the cache, calling
> FileSystem.get() returns a stale DRFS that throws 'filesystem closed'
> exceptions.
