reassign Partition leader

Hi All,

Here is my test scenario.

There are two broker(A,B) and make one topic which has two partition.

and then, A is leader of partition #0 and B is leader of partition #1.

Producer and consumer work well.

If, B broker is down, A become leader of partition #0 and #1.

That is good. and work well.

But, When broker B run again, B is not leader of #1. Broker A receive all
messages.

In that case,

I want to reassign a leader of partition #1 from A to B.

Is it possible??

Thanks~ :)

Yes, there is an admin tool PreferredReplicaLeaderElectionCommand that you
can run.

Thanks,
