I'm currently aware of the following issues:
* quite a few tests in flink-runtime fail; this is mostly due to a missing
integration into the MockEnvironments. Fix coming up
* there is an issue in the IO metrics for operations with multiple outputs.
This one is a bit more tricky, but a not-so-pretty solution is on the way.
> Expose metrics to graphite, ganglia and JMX.
