As far as I can see, transform method accepts only dataframe. Is there a way to somehow apply model to transform a single vector?

There is not, or at least there is not if you ask about core Spark. Related feature request is tracked by SPARK-10413 and SPARK-10884 but none have seen much progress so far.

There exist external libraries which might address this problem, some mentioned in How to serve a Spark MLlib model?.

Try to change the vector to a single row data Frame. And then run the model on it
