Concatenate? no. It doesn't make sense in this context to think about one potentially infinite stream coming after another one. Do you just want the union of batches from two streams? yes, just union(). You can union() with non-streaming RDDs too.

Is it possible to concatenate or append two Dstreams together? I have an incoming stream that I wish to combine with data that's generated by a utility. I then need to process the combined Dstream.
