Review Comment:
this import has snuck into the wrong place, just because of the move off
guava. putting it with the "real" hadoop imports avoids problems later

> If a node in the datacenter crashes while processing an operation,
> occasionally it can leave the Storage-internal blob tracking metadata in an
> incomplete state. We expect this to happen occasionally, and so all API’s
> are designed in such a way that if this incomplete state is observed on a
> blob, the situation is resolved before the current operation proceeds.
> However, this incident has exposed a bug specifically with the Rename API,
> where the incomplete state fails to resolve, leading to this incorrect
> failure. As a temporary mitigation, if any other operation is performed on
> this blob – GetBlobProperties, GetBlob, GetFileProperties, SetFileProperties,
> etc – it should resolve the incomplete state, and rename will no longer hit
> this issue.
