Subject [GitHub] spark pull request: [SPARK-10955][streaming] Disable dynamic alloc...

    Checking which types of dstreams are used and what configurations are used and accordingly
throwing errors seems to be complicated and brittle. I think its best to throw a warning.

    
    In general, if they are not using WAL or reliable sources, they should be aware that they
are going to loose data under failures anyways, and they should be aware of that anyways.
Dynamic allocation really does not aggravate the problem significantly more.
