Thanks for your answer.
The problem is that both slots are seized in the one node. Of course if this 
node has enough free slots.
Another nodes idle. I want to utilize cluster resource little bit more.
May be the other deployment modes allow it.

BR, Evgeny.

Тема: Re: Running streaming job on every node of cluster

Hi Evgeny,
I tried to reproduce your example with the following code, having another
console listening with "nc -l 12345"

env.setParallelism(2);
env.addSource(new SocketTextStreamFunction("localhost", 12345, " ", 3))
                               .map(new MapFunction<String, String>() {
                                               @Override
                                               public String map(final String 
s) throws Exception { return s; }
                               })
                               .addSink(new DiscardingSink<String>());

This way, I do get a source with parallelism 1 and map & sink with parallelism
2 and the whole program accompanying 2 slots as expected. You can check in the
web interface of your cluster how many slots are taken after executing one
instance of your program.

How do you set your parallelism?
