org.apache.kafka.common.errors.TimeoutException: Failed to send request after 5000 ms

[Abhimanyu Nagrath]

I am using Kafka V 0.10.2 (8 Cores, 16 GB RAM). While executing the command

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

Sometimes I am getting this exception :

    Exception in consumer group command (kafka.admin.ConsumerGroupCommand$)
    java.lang.RuntimeException: Request GROUP_COORDINATOR failed on brokers
List(localhost:9092 (id: -1 rack: null))

    at kafka.admin.ConsumerGroupCommand$.main(ConsumerGroupCommand.scala:73)
    at kafka.admin.ConsumerGroupCommand.main(ConsumerGroupCommand.scala)

Am I missing something? How to fix it?
