ConsumerRebalanceListener not being invoked
Hello Kafka Team,
I just cannot get my registered "ConsumerRebalanceListener" to be invoked.
GitHub Commit for a full picture if that helps:
https://github.com/slydogshah/appGalCloud/commit/323a447929a17d8449b931a2972a746251dce495
Here is my KafkaConsumer bootstrap code
----

config.put("value.serializer",

//config.put("session.timeout.ms", 30000);
this.kafkaConsumer = new KafkaConsumer<String, String>(config);
KafkaRebalanceListener rebalanceListener = new
KafkaRebalanceListener(this.topicPartitions);
this.kafkaConsumer.subscribe(topics, rebalanceListener);
