Even not working optimally?
The even
mode in balance
is the following:
even - This is a specialized type for clusters which have topics that have a number of partitions that are a multiple of the number of brokers. The module assures that every broker has exactly the same number of partitions for each topic.
Yet the code tries to SSH to my brokers?
[ec2-user@ip-172-31-12-216 ~]$ kafka-assigner -z $ZK_HOST -e balance --types even

I would have guessed the even
module could just connect to Zookeeper to distribute partitions evenly?
