Re: unoin streams not working for streams > 3
I assume you're using the receiver based stream (createStream) rather than createDirectStream? Receivers each get scheduled as if they occupy a core, so you need at least one more core than number of receivers if you want to get any work done. Try using the direct stream if you can't combine receivers. On Mon, Sep 14, 2015 at 11:10 PM, Василец Дмитрийwrote: > I use local[*].

How many cores are you assigning to your spark streaming job?
