> Priority: Blocker
> Fix For: 0.8

>
> Consumer may not notice new partitions because the propagation of the
> metadata to servers can be delayed.
> Options:
> 1. As Jun suggested on KAFKA-956, the easiest fix would be to read the new
> partition data from zookeeper instead of a kafka server.
> 2. Run a fetch metadata loop in consumer, and set auto.offset.reset to
> smallest once the consumer has started.
> 1 sounds easier to do. If 1 causes long delays in reading all partitions at
> the start of every rebalance, 2 may be worth considering.
>
> The same issue affects MirrorMaker when new topics are created, MirrorMaker
> may not notice all partitions of the new topics until the next rebalance.
