I don't understand the hate for Zookeeper.

Setting up a Zookeeper ensemble is not that hard, they're light on resources and and basically zero maintenance.

Sure, a basic ensemble isn't that hard. But securing it is a world of pain and misery.

The ZK development API is also pretty much awful. Apache Curator (which wraps around the ZK API and implements a bunch of common "recipes") makes it less painful, but it really ought to be part of ZK proper.

God forbid you hit a bug in ZK too, as there are 5 people in the world who properly understand that system - there is nobody to help.

Agreed. I’ve been running Kafka clusters at a few companies now, one that was at a massive Fortune 500 and Zookeeper was the least of my problems.

I’m still glad to see it go away, one less operational dependency the better.
