-------------------------------------
Summary: Kafka integration tests failing in "airplane mode"
Key: FLINK-7066
URL: https://issues.apache.org/jira/browse/FLINK-7066
Project: Flink
Issue Type: Bug
Reporter: Piotr Nowojski
Assignee: Piotr Nowojski
Tests KafkaXXXProducerITCase are failing on my laptop in airplane mode. It
seemed to have something to do with some service listening on wrong interface,
when client tries to connect to different host. Strangely tests for Kafka010
and Kafka011 fails with different error, but there is the same fix for them
(maybe in Kafka010 original exception is masked by some other error). Kafka
0.11 tests fails like this:

I think the issue is that there is someone listening on
fe80:0:0:0:165d:140b:f597:e019 (note that this is ipv6 address from some
virtual utun0 interface on my machine), while JobClient tries to connect to
"localhost" - which fails. When I enable wifi and connect to any network and
log looks like this:
