Currently I'm low on time for this. State so far:
* "downgrading" the upgrade to Flink 1.3.x seems to fix a build problem
with an older spark version
* on my travis the other branches (master, branch-0.8) error out therefore
it is hard to look at failed tests
It would be cool to go for Flink 1.4.x (as 1.5.x is on the horizon) but
that would require switching to scala 2.11 which breaks older spark stuff, so
this is not an option right now.
