> While connecting the kafka with zookeeper at a custom path, in the broker-0, this error message pops up-
> {{ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer) kafka.common.InconsistentClusterIdException: The Cluster ID 2yEEELdtRfKOJQiEurdoFg doesn't match stored clusterId Some(H8dPCWwzRCK4eDmH3l5vvA) in meta.properties. The broker is trying to join the wrong cluster. Configured zookeeper.connect may be wrong. at kafka.server.KafkaServer.startup(KafkaServer.scala:220) at kafka.server.KafkaServerStartable.startup(KafkaServerStartable.scala:44) at kafka.Kafka$.main(Kafka.scala:84) at kafka.Kafka.main(Kafka.scala)}}
