Kafka is super buzzword nowadays in Bigdata space, so I thought to share some of exceptions and troubleshooting steps that I have encountered till now using Kafka in my project.
Issue 1 # Error while fetching metadata with correlation id 0 : {Visitor=LEADER_NOT_AVAILABLE (org.apache.kafka.clients.NetworkClient)
Fix : There could be many reason of this failure but I resolved it by updating
host.name=localhost
advertised.host.name=localhost
in $Kafka_home/config/server.properties where localhost is kafka’s server hostname. Basically it was happening due to incorrect network binding of my laptop’s wireless interface.
Issue 2 # <Next_Exception_will_be_listed_soon>
I have noticed you don’t monetize your site, don’t waste your traffic,
you can earn extra cash every month because you’ve
got high quality content. If you want to know how to make extra
