Now that the move has stopped/completed.  Verify if there are no under-replicated OR offline partitions and also verify if there are 3 replicas and all are in sync (depends on your replication factor) You can delete those partitions manually and just restart the broker.  If replicas are out of sync they must come back in sync if unclean.leader.election is true  ...

Yes. What we are doing here is that we are stopping the reassignment that is not progressing. And to do that you run it with the original json file and it will stop and revert back.  ... View more

Do you have the original assignment ?  You can stop it by passing the original assignment. It will just revert back. I did this couple of times and it works.    Now regarding why its not completing can be an IO issue.  Did you configure this value in the cluster num.replica.alter.log.dirs.threads. ? If  not you might have to set it.  Also might have to set intra.broker.throttled.rate using the safety valve.    I read it in this KIP https://cwiki.apache.org/confluence/display/KAFKA/KIP-113%3A+Support+replicas+movement+between+log+directories    Test in staging and then you can implement in prod.  ...
