Jun Rao commented on KAFKA-948:
-------------------------------
Currently, if you want to replace a failed broker, you will need to bring up
the broker on another machine with the same broker id. kafka-reassign-topic.sh
won't succeed until the old replicas are removed, which won't happen if the
broker hosting an old replica is down.
> ISR list in LeaderAndISR path not updated for partitions when Broker (which
> is not leader) is down

> When the broker which is the leader for a partition is down, the ISR list in
> the LeaderAndISR path is updated. But if the broker , which is not a leader
