How To Fix - Deploying Kafka on AWS Error ?

---

In this post , we will see How To Fix - Deploying Kafka on AWS Error . While deploying Kafka on AWS , we sometimes see error as below -

kafka.common.KafkaException: Socket server failed to bind to hostname:9092: Cannot assign requested address.

This mostly relates due to the Missing IP Address or IP Address conflict in the configuration. There are two main properties , you need to verify and check if they have been properly defined and used. Both these properties are part of server.properties config file. The properties are - Listeners & Advertised Listeners. Cross-check your server.properties files - I have given a sample as to how these should look like.  

\# In Server.properties file , make changes 

listeners=PLAINTEXT://<aws-Public-elastic-ip-address>:9092  

advertised.listeners=PLAINTEXT://<aws-Public-elastic-ip-address>:9092
