    I would suggest using a random port range.

> I saw multiple failures of the {{JmxReporterTest}} most likely due to a port conflicts.
The test relies on the default JMX reporter port range, which spans 5 ports. Running on Travis
with multiple concurrent builds and bad timings, this can lead to port conflicts.
> Some example failed runs:
> https://s3.amazonaws.com/archive.travis-ci.org/jobs/141999066/log.txt (one out of 5 jobs
failed)
> https://travis-ci.org/uce/flink/builds/141917901 (all 5 jobs failed)
> I propose to take the fork number into account (like the forkable Flink testing cluster)
and configure a larger port range.
