Cmak: Error while fetching metadata with correlation id 540 : {__consumer_offsets=UNKNOWN}

[ghost]

Hi,
I'm running kafka manger against my Kafka cluster and i'm getting a lot of the following error in the kafka manager log files:

[warn] o.a.k.c.NetworkClient - Error while fetching metadata with correlation id 540 : {__consumer_offsets=UNKNOWN}
[warn] o.a.k.c.p.Errors - Unexpected error code: 38.

I tried googling the following error and couldn't find any reason for it.
I tested the connectivity between the kafka manager to the zookeeper and brokers and the ports are open and i'm able to connect

Any ideas what i'm doing wrong?

Broker node must config /etc/hosts, as follows:

hostname
TIKY

sudo vi /etc/hosts
192.168.3.9 TIKY

Hey, I encountered the same error. kafka-manager correctly displays info about brokers etc, but I'm not sure if JMX is working and/or showing correct data (as it seems no data is flowing through kafka) so want to eliminate all possibilities.
