-------------------------------------------
Summary: Kafka restart on a Kerberoized cluster fails (happens
some times)
Key: AMBARI-20015
URL: https://issues.apache.org/jira/browse/AMBARI-20015
Project: Ambari
Issue Type: Bug
Components: ambari-server
Reporter: Bharat Viswanadham
On a Kerberoized cluster when we restart Kafka, Kafka start fails with below
error
[2016-02-29 08:44:15,339] FATAL [Kafka Server 1001], Fatal error during
KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)
java.lang.RuntimeException: A broker is already registered on the path
/brokers/ids/1001. 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.
