Subject [jira] [Updated] (KAFKA-4975) Kafka process is running, but not listening to 9092 port
Date Wed, 29 Mar 2017 13:38:41 GMT

     [ https://issues.apache.org/jira/browse/KAFKA-4975?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Rafael Telles updated KAFKA-4975:
---------------------------------
    Description: 
I have two clusters of Kafka brokers, one of them (with 15 brokers + 3 Zookeeper servers)
became sick (a lot of under-replicated partitions, throwing a lot of NotEnoughReplicasExceptions).
I logged in some of the brokers that other couldn't connect to, and I found out that they
were all running their Kafka process, but they were not listening to the default TCP port
(9092) as expected:
