I did see intermittent failures once with one of the tests in
`org.apache.hadoop.fs.contract.s3a.ITestS3AContractRootDir`. I can't remember
which test it was, but when I ran just that file immediately after the failure,
it passed. Every other time I've run `mvn verify` they've all passed.

> If an application crashes during an S3ABlockOutputStream upload, it's
> possible to complete the upload if fast.upload.buffer is set to disk by
> uploading the s3ablock file with putObject as the final part of the multipart
> upload. If the application has multiple uploads running in parallel though
> and they're on the same part number when the application fails, then there is
> no way to determine which file belongs to which object, and recovery of
> either upload is impossible.
> If the temporary file name for disk buffering included the s3 key, then every
> partial upload would be recoverable.
