Description

There are several Zookeeper client settings that may be used to connect to ZK.

Currently, it seems only very few zookeeper.* settings are supported in Kafka's server.properties file. Wouldn't it make sense to support all zookeeper client settings there or where would that need to go?

I.e. for using Zookeeper 3.5 with TLS enabled, the following properties are required:

zookeeper.clientCnxnSocket
zookeeper.client.secure
zookeeper.ssl.keyStore.location
zookeeper.ssl.keyStore.password
zookeeper.ssl.trustStore.location
zookeeper.ssl.trustStore.password

It's obviously possible to pass them through "-D", but especially for the keystore password, I'd be more comfortable with this sitting in the properties file than being visible in the process list...
