In my experience there is a bit of a learning curve until you understand how each of the parts fit together and how to optimize for your use case. ZooKeeper indeed was one of those pain points, but once you get it stable there is practically no need to touch it.
I found the tips in the docs on optimizing ZK really helpful [1].
Anoter mistake we did early on with ZooKeeper, that caused us a lot of pain was running it with network attached disks (we ran ClickHouse+ZK in the cloud). Once we switched to local disks, 99% problems disappeared.
