Description

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.
