Ewen Cheslack-Postava commented on KAFKA-3782: ---------------------------------------------- Analysis elsewhere has shown that this seems to be a session timeout issue where we are unable to make progress on actually delivering data in the test. This is obviously not ideal, but hasn't so far indicated an underlying problem with the system. We need to at least tweak the timeouts/frequency of bouncing workers to allow the test to make progress. > Transient failure with > kafkatest.tests.connect.connect_distributed_test.ConnectDistributedTest.test_bounce.clean=True > --------------------------------------------------------------------------------------------------------------------- > > Key: KAFKA-3782 > URL: https://issues.apache.org/jira/browse/KAFKA-3782 > Project: Kafka > Issue Type: Bug > Components: KafkaConnect > Affects Versions: 0.10.0.0 > Reporter: Liquan Pei > Assignee: Ewen Cheslack-Postava > Priority: Minor > Fix For: 0.10.1.0 > > > For commit 946ae60 > max() arg is an empty sequence > Traceback (most recent call last): > File > "/var/lib/jenkins/workspace/system-test-kafka-0.10.0/kafka/venv/local/lib/python2.7/site-packages/ducktape-0.5.1-py2.7.egg/ducktape/tests/runner.py", > line 106, in run_all_tests > data = self.run_single_test() > File > "/var/lib/jenkins/workspace/system-test-kafka-0.10.0/kafka/venv/local/lib/python2.7/site-packages/ducktape-0.5.1-py2.7.egg/ducktape/tests/runner.py", > line 162, in run_single_test > return self.current_test_context.function(self.current_test) > File > "/var/lib/jenkins/workspace/system-test-kafka-0.10.0/kafka/venv/local/lib/python2.7/site-packages/ducktape-0.5.1-py2.7.egg/ducktape/mark/_mark.py", > line 331, in wrapper > return functools.partial(f, *args, **kwargs)(*w_args, **w_kwargs) > File > "/var/lib/jenkins/workspace/system-test-kafka-0.10.0/kafka/tests/kafkatest/tests/connect/connect_distributed_test.py", > line 321, in test_bounce > sink_seqno_max = max(sink_seqnos) > ValueError: max() arg is an empty sequence -- This message was sent by Atlassian JIRA (v6.3.4#6332)
