Guozhang Wang commented on KAFKA-990:
-------------------------------------

Just one more comment: as for Swapnil's 16, currently partition id 0 is also used for AddPartitionCommand. Shall we change that also?

> 1. The tool does not register for IsrChangeListener on controller failover.
> 2. There is a race condition where the previous listener can fire on controller failover and the replicas can be in ISR. Even after re-registering the ISR listener after failover, it will never be triggered.
> 3. The input the tool is a static list which is very hard to use. To improve this, as a first step the tool needs to take a list of topics and list of brokers to do the assignment to and then generate the reassignment plan.
