It's been some time since you last post, is this patch available now. Also
we are doing following manual steps to update existing topic to use new
1) stop all zookeepers
2) stop all kafka brokers
3) clean data dir or zookeepers and kafka
4) start zookeepers and kafka.
This involves both downtime and loosing data. Is there a better way to
update existing topics to use new partitions until patch is available..?
