------------------------------
Summary: transient unit test failure UncleanLeaderElectionTest
Key: KAFKA-1638
URL: https://issues.apache.org/jira/browse/KAFKA-1638
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 0.8.2
Reporter: Jun Rao
Saw the following transient unit test failure.
kafka.integration.UncleanLeaderElectionTest > testUncleanLeaderElectionEnabled
FAILED
java.lang.RuntimeException: A broker is already registered on the path
/brokers/ids/1. This probably indicates that you either have configured a
brokerid that is already in use, or else you have shutdown this broker and
restarted it faster than the zookeeper timeout so it appears to be
re-registering.
