> 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.
