[Kafka-users] How to create the initial zookeeper chroot path for zk.connect? - Grokbase

1. Install a single node Kafka, three nodes zookeeper instances

     kafka1
     zookeeper1
     zookeeper2
     zookeeper3

2. Using a simple Kafka config, able to start without error in the log

     brokerid=1
     log.dir=/data/kafka
     zk.connect=zookeeper1:2181,zookeeper2:2181,zookeeper3:2181

3. Now, create a path in zookeeper1

     zkCli.sh -server zookeeper1:2181

         ls /
         [consumers, brokers, zookeeper]
         create /testkafka ''
         ls /
         [testkafka, consumers, brokers, zookeeper]

Quit & Done.

4. Verify from zookeeper2

     zkCli.sh -server zookeeper2:2181
         ls /
         [testkafka, consumers, brokers, zookeeper]

Seems ok

4. Update kafka config and restart


zk.connect=zookeeper1:2181/testkafka,zookeeper2:2181/testkafka,zookeeper3:2181/testkafka

Restart and have the error
