Jiangtao Liu commented on KAFKA-6961:
-------------------------------------

I encounter the same issue after I move Kafka server to new EC2 server.

so any idea to solve it? or simply ignore it since our replica is functional 
well. 

> UnknownTopicOrPartitionException & NotLeaderForPartitionException upon 
> replication of topics.

> When we tries producing records to each specific partition, it works fine and 
> also log size across the replicated brokers appears to be equal, which means 
> replication is happening fine.
> Attaching the two stack trace files.

> Why are these stack traces appearing ? can we ignore these stack traces if 
> its some spam messages ?
