The existing signature for open() is a remnant of the past.
We currently recommend to pass all arguments through the constructor and
store them in fields.
You can of course also pass a Configuration containing all parameters.

Hi all!
A RichMapFunction [1] provides a very handy setup method
RichFunction#open(org.apache.flink.configuration.Configuration) which
consumes a Configuration instance as an argument, but this argument
doesn't bear any configuration parameters because it is always passed
to the method as a new instance. [2] depicts the problem.
Is there any way to pass configuration parameters to the
RichFunction#open method via the Configuration parameter? Or is it a bug?
P.S. I'm using flink 1.3
Thanks in advance!
