kafka broker restart failed without me knowing why
I’m facing an issue with my 3-node Kafka cluster, and perhaps you can help me troubleshoot.
Unable to start kafka Server on Windows
I was trying to start kafka Server after i started zookeeper but i run in some error. I have downloaded zookeeper from the downloadpage and i could sucessfully start it, because when i try to start zookeeper from kafka installation i get a syntax error by cmd. However the same problem when i try to start kafka server, i get the following output:
C:kafka>.binwindowskafka-server-start.bat .configserver.properties
Syntaxfehler.
Does Cmak still connects to zookeeper and not brokers? Can someone help me with the steps/configuration for cmak to connect to SSL zookeeper?
I am having cmak in our environment. Can someone help me with the steps or configuration to connect cmak to SSL zookeeper
