Hello Michalis,

Welcome back! :)

Yes, indeed, the issue got solved.
I would propose you write the missing tests for the Apache Flink platform. Here 
below the steps to follow (which are the two issues I will create right now):
(1) Re-run our benchmark jobs to make sure they are all working and improve the 
readme file for how to run the benchmarks. This issue will put you into context 
to solve the second issue below.
(2) Write the missing tests for Flink. Currently, we already have tests for 
some operators of Flink but not all operators are covered. Therefore, we need 
to write those missing tests, for which you can follow their counterparts in 
the Spark platform.

Would that sound good for you?

Best,
Jorge
