> {{RetriableFileCopyCommand.CopyReadException}} is double-wrapped via
> # via {{RetriableCommand::execute}}
> # via {{CopyMapper#copyFileWithRetry}}
> before {{CopyMapper::handleFailure}} tests 
> {code}
> if (ignoreFailures && exception.getCause() instanceof
>             RetriableFileCopyCommand.CopyReadException
> {code}
> which is always false.
> Orthogonally, ignoring failures should be mutually exclusive with the atomic option otherwise an incomplete dir is eligible for commit defeating the purpose.
