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

[Abhimanyu Nagrath]

Hi, 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 <groupName>

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.

Regards,
Abhimanyu
