> Key: KAFKA-2146
> URL: https://issues.apache.org/jira/browse/KAFKA-2146
> Project: Kafka
> Issue Type: Bug
> Components: admin
> Affects Versions: 0.8.2.0
> Reporter: chenshangan
> Priority: Minor
> Fix For: 0.8.3
>
>
> TopicCommand provide a tool to add partitions for existing topics. It try to
> find the startIndex from existing partitions. There's a minor flaw in this
> process, it try to use the first partition fetched from zookeeper as the
> start partition, and use the first replica id in this partition as the
> startIndex.
> One thing, the first partition fetched from zookeeper is not necessary to be
> the start partition. As partition id begin from zero, we should use partition
> with id zero as the start partition.
> The other, broker id does not necessary begin from 0, so the startIndex is
> not necessary to be the first replica id in the start partition.
