> Kafka not trying re-register back in Zookeeper
> ----------------------------------------------
>
> Key: KAFKA-3893
> URL: https://issues.apache.org/jira/browse/KAFKA-3893
> Project: Kafka
> Issue Type: Bug
> Reporter: chaitra
> Priority: Critical
>
> Kafka version used : 0.8.2.1
> Zookeeper version: 3.4.6
> We have scenario where kafka is not trying to register back in zookeeper,
> because of which we don't see the broker id in the zookeeper path
> /brokers/ids.
> In our scenario its been almost 24 hours since there is active connection
> established to zookeeper , But I don't see any "connection exception after
> timeout in zookeeper"
> The zookeeper conection timeout is set to 6000ms in server.properties
> Hence Kafka not participating in cluster
