    I think so. I don't know whether the configured value is respected though.

> 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 :)
