Hi Guys,

I installed kafka in my system and also configured zookeeper. But I am getting the below error, when tried to start kafka-server.

$ bin/kafka-server-start.sh config/server.properties Exception in thread "main"

Hi@akhtar,

As the above error shows that the version is not supported with your current environment. 

java.lang.UnsupportedClassVersionError: kafka/Kafka : Unsupported major.minor version 52.0 

So, uninstall this version and try with different version.

Hope it will help.
