Topic: HELP: Trying to configure Zookeeper and Kafka

[sunglant]

Hello everyone,

I am trying to stand up a simple quorum and configure kafka and zookeeper to handle large to very large sized payloads. All my builds are on RHEL 7.4, and while I have set each system up they keep falling down. I assume I missed something in a configuration file. but I don't know which ones to look at. This build I am working with is a test which is not getting any data or payloads at the moment. I am trying to write up the build guide for automation purposes later but if I cannot get the two systems to stand up and play nice then I am proving einstin's theory of insanity.

Any assistance related to which files I need to modify or what I need to put in them would be very helpful.

Thank you.

additional I cannot get zookeeper to go into a quorum state I get the following errors
