Matthias commented on FLINK-18842:
----------------------------------
I discussed the issue with [~rmetzger]: It is hard to debug since it's
happening within the Docker build. It does not have to be related to the
{{connection refused}} error that appears since it's also appearing in
succeeding builds.
I created a new branch which runs this test multiple times trying to reproduce
the problem without success:
* [Build
#38|https://dev.azure.com/mapohl/flink/_build/results?buildId=38&view=logs&j=aba23331-5614-58a0-ecb7-9c9e540c50fe&t=b30be84f-4d76-59f8-beed-6fd3501240e4]
- 50 runs without any error
* [Build
#39|https://dev.azure.com/mapohl/flink/_build/results?buildId=39&view=logs&j=1f3ed471-1849-5d3c-a34c-19792af4ad16&t=0d2e35fc-a330-5cf2-a012-7267e2667b1d]
- 100 runs without any error
* [Build
#40|https://dev.azure.com/mapohl/flink/_build/results?buildId=40&view=logs&j=1f3ed471-1849-5d3c-a34c-19792af4ad16&t=0d2e35fc-a330-5cf2-a012-7267e2667b1d]
- 100 runs without any error (the failure was caused by another test that
tried to download Kafka (cmp.
[FLINK-19158|https://issues.apache.org/jira/browse/FLINK-19158])
*
We're gonna wait for [~chesnay] to have a look at the issue.
