Hello Kafka User Community,

In our project(as part of kafka  failover evaluation), we have a single cluster 
with five kafka nodes (five partition), three consumers (attached to single 
group) and single Zookeeper node. As soon as cluster startups, we see leader 
election per partition and each consumers discovers the group co-ordinator. 
Now, when manually shutdown kafka service in the co-ordinator node, entire 
cluster goes down (means no publish/subscribe of messages happening).

As per Kafka wiki  co-ordinator 
 we see coordinator failover handling as part of kafka cluster. Kindly let us 
know anyone  in the community has encountered this earlier or any known 
solution available.

Best Regards,
Krishnakumar G
