how to add broker id manually to zookper cli

Question

we have kafka cluster with 3 brokers machines and 3 zookeeper servers machines

all servers are installed on redhat 7.2 version

but when we run the following cli ( to know that all brokers ids are exist in zookeeper , we get:

zookeeper-shell.sh zoo_server:2181 <<< "ls /brokers/ids"

WATCHER::

WatchedEvent state:SyncConnected type:None path:null
[3, 2]

instead to get that:

[3, 2 , 1]

we checked the first broker ( kafka01 ) by searching errors in server.log

And we not see any related error in the log!

port 2181 from kafka broker to zookeeper machine is working

we also restart kafka01 , but this not help to get the broker id in zookeeper cli

we try also to restart all zookeeper servers ( there are 3 ) , and then again to restart kafka01 , but still without results

so any suggestion to this behavior?

can we add the missing broker to zookeeper cli ? , if yes then how?

but no info about how to add id to zookeeper

please let me know what logs you want , but as I said kafka01 is ok , not see any error from server.log , also on zookeeper server logs not see any error — jessica
kafka configuration is part in ambari ( kafka configuration in ambari is correct ) — jessica
as I said all kafkla broker are the same configuration ( in ambari ) , the server.log not include any error , so why you not give attention to what I am saying? , please be more specific? — jessica
That simply sounds like the kafka01 server is simply not connected/configured with the rest of the cluster. So, the "cluster" is really only brokers 2 and 3 right now. — mjuarez
in ambari - I see in kafka --> config three kafka , I not make any change , this behavior is in the last week , before that everything was ok — jessica
