Description

I am getting an error while running Kafka tests:

Traceback (most recent call last): File "/home/jenkins/workspace/system-test-kafka_5.3.x/kafka/venv/local/lib/python2.7/site-packages/ducktape-0.7.5-py2.7.egg/ducktape/tests/runner_client.py", line 132, in run data = self.run_test() File "/home/jenkins/workspace/system-test-kafka_5.3.x/kafka/venv/local/lib/python2.7/site-packages/ducktape-0.7.5-py2.7.egg/ducktape/tests/runner_client.py", line 189, in run_test return self.test_context.function(self.test) File "/home/jenkins/workspace/system-test-kafka_5.3.x/kafka/tests/kafkatest/tests/connect/connect_rest_test.py", line 89, in test_rest_api assert set([connector_plugin['class'] for connector_plugin in self.cc.list_connector_plugins()]) == \{self.FILE_SOURCE_CONNECTOR, self.FILE_SINK_CONNECTOR} File "/home/jenkins/workspace/system-test-kafka_5.3.x/kafka/tests/kafkatest/services/connect.py", line 218, in list_connector_plugins return self._rest('/connector-plugins/', node=node) File "/home/jenkins/workspace/system-test-kafka_5.3.x/kafka/tests/kafkatest/services/connect.py", line 234, in _rest raise ConnectRestError(resp.status_code, resp.text, resp.url) ConnectRestError

From the logs, I see two messages:

[2019-05-23 16:09:59,373] INFO REST server listening at http://172.31.39.205:8083/, advertising URL http://worker1:8083/ (org.apache.kafka.connect.runtime.rest.RestServer)

and

[2019-05-23 16:10:00,738] INFO REST resources initialized; server is started and ready to handle requests (org.apache.kafka.connect.runtime.rest.RestServer)

it takes 1365 ms to actually load REST resources, but the test is waiting on a port to be listening.
