Hi David and all, Sorry, I found a bug KAFKA-18979 <https://issues.apache.org/jira/browse/KAFKA-18979>, and in my opinion, it should be a blocker. But I'd like to get @José Armando García Sancio <jsan...@confluent.io> 's confirmation.
BTW, for the system tests: > * kafkatest.tests.connect.connect_distributed_test - These tests are flaky in our test infrastructure but they pass locally. It passed in our internal environment. > * kafkatest.tests.core.network_degrade_test - This is not a blocker as it does not test any Kafka bits besides Trogdor. The failed tests are all passed in our internal environment. So system tests look good to me. Thanks.
