Error: Executing consumer group command failed due to Request GROUP_COORDINATOR failed on brokers List(localhost:9092 (id: -1 rack: null))

Question

I am using single node Kafka cluster(version 0.10.2) and single node zookeeper (3.4.9). I am having approx 310 topics with Avg 100 partitions per topic. On Kafka broker when I am running the command to check consumer status in a group

./kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe --group

Most of the time it is throwing an error:

Error: Executing consumer group command failed due to Request GROUP_COORDINATOR failed on brokers List(localhost:9092 (id: -1 rack: null))

and rest of the time it is showing the correct result.

I googled it but was not able to find the exact result of this error.Can someone tell me how to fix this error? Any help would be appreciated.

Answer 1

Are you sure you can connect to localhost:9092?

I get this error whenever the url to the bootstrap server is wrong.

Try whatever other host and you will see the same error.
