    The default UI refresh interval is larger than the history server refresh 
interval. I think both should be the same. I would go with 10s for both.

> Right now its not possible to analyze the job results for jobs that ran on 
> YARN, because we'll loose the information once the JobManager has stopped.
> Therefore, I propose to implement a "Flink History Server" which serves  the 
> results from these jobs.
> I haven't started thinking about the implementation, but I suspect it 
> involves some JSON files stored in HDFS :)
