             Summary: Memory records is not writable in MirrorMaker
                 Key: KAFKA-3147
                 URL: https://issues.apache.org/jira/browse/KAFKA-3147
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.9.0.0
            Reporter: Meghana Narasimhan


Hi,
We are running a 3 node cluster (kafka version 0.9) and Node 0 also has a few 
mirror makers running. 
When we do a rolling restart of the cluster, the mirror maker shuts down with 
the following errors.

Curious if the NOT_LEADER_FOR_PARTITION is because of a potential bug hinted at 
in the thread , 
http://mail-archives.apache.org/mod_mbox/kafka-users/201505.mbox/%3ccajs3ho_u8s1xou_kudnfjamypjtmrjlw10qvkngn2yqkdan...@mail.gmail.com%3E
   

And I think the mirror maker shuts down because of the "abort.on.send.failure" 
which is set to true in our case.
