Although we talked about using the new system you've implemented here, we
have to consider backward compatibility.
Since the original behavior is already visible to users in Drill 1.8, I
think we need to leave your original design.
At some point, we'll need to rationalize how Drill handles temp files and
storage in DFS. But, until then, your 1.8 design is fine.
