Description

http://confluent-kafka-system-test-results.s3-us-west-2.amazonaws.com/2016-04-05--001.1459840046--apache--trunk--31e263e/report.html

The version of the test fails in this case is:
Module: kafkatest.tests.client.consumer_test
Class: OffsetValidationTest
Method: test_broker_failure
Arguments:
{
"clean_shutdown": true,
"enable_autocommit": false
}

and others passed. It's unclear if the parameters actually have any impact on the failure.

I did some initial triage and it looks like the test code isn't seeing all the group members join the group (receive partition assignments), but it appears from the logs that they all did. This could indicate a simple timing issue, but I haven't been able to verify that yet.
