> Reporter: superheizai
> Priority: Major

> I have topic with 256 parititons.
> Firstly, I generate the topic partitions with their brokerIds with
> kafka-reassign-partitions generate.
> Seconld, I add a brokerId for each partition.
> Then, I run kafka-reassign-partitions, some partitions increased their
> replication factor, but the others stoped.
> When I read log controller.log, some partitions' replication factors
> increased. Then I remove these paritions which replication factor base been
> increased and run kafka-reassign-partitions again, but no log in
> controller.log, all paritions are "still in progress", no network flow
> changed when watch zabbix network.
