Modify kafka's zookeeper.connect configuration

[#1]

Kafka is installed through ambari, zookeeper.connect the default installation path is zookeeper root directory (/), looks messy. I would like to modify the zookeeper.connect configuration, put it into / kafka, which I should modify the configuration? But hortonworks official website document that is not recommended to modify.

@xling it It is ok to modify the root zknode. It is just that you need to use the same config when ever you try to connect to kafka.
