Jiangjie Qin commented on KAFKA-2406:
-------------------------------------
[~junrao], sure. I'm testing the new patch and will update the findings later.
Also another problem in current code is that it is creating znode in
/isr_change_notification, but we are deleting path from /config. So the znode
never got deleted.
> ISR propagation should be throttled to avoid overwhelming controller.

> We need to throttle the ISR propagation rate to avoid flooding in controller

> shutdown or cluster startup.
