I¹m trying out 1.0 on a set of small Spark Streaming tests and am running
into problems. Here¹s one of the little programs I¹ve used for a long
time ‹ it reads a Kafka stream that contains Twitter JSON tweets and does
some simple counting. The program starts OK (it connects to the Kafka
stream fi
Hey Jim,
Do you see the same behavior if you run this outside of eclipse?
Also, what happens if you print something to standard out when setting
up your streams (i.e. not inside of the foreach) do you see that? This
could be a streaming issue, but it could also be something related to
the way it'
Also one other thing to try, try removing all of the logic form inside
of foreach and just printing something. It could be that somehow an
exception is being triggered inside of your foreach block and as a
result the output goes away.

Few more suggestions.
1. See the web ui, is the system running any jobs? If not, then you may
need to give the system more nodes. Basically the system should have more
cores than the number of receivers.
2. Furthermore there is a streaming specific web ui which gives more
streaming specific data.
