How can I set configuration of process function from job's main?

[Main Frame]

Hi guys! Iam newbie in flink and I have probably silly question about streaming 
api.

So for the instance:

I trying to apply SomeProcessFunction to stream1

…
DataStream<ObjectNode> stream2 = stream1.process(new 
MyProcessFunction()).name("Ingest data»);
…

I have created package-private class with MyProcessFunction which extends 
ProcessFunction.

class MyProcessFunction extends ProcessFunction<ObjectNode, ObjectNode> {

    @Override
    public void open(Configuration parameters) throws Exception {
         ...
    }
    …
}

How can I set parameters variable before execution of MyProcessFunction?
