I've been struggling with this exact issue for a very, very long time and was happy to finally have found this... *BUT* is this documented anywhere? Was it just me that couldn't find it? It seems that "local" is a perfectly reasonable thing to assume will work, but when you never get output that just seems broken. As I said, maybe I just didn't see it somewhere so apologies if that's the case, but if not this should be a big red warning on the javadoc, tutorials, etc. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/streaming-questions-tp3281p8655.html Sent from the Apache Spark User List mailing list archive at Nabble.com.
