If time permits, it would be great to have both KAFKA-2397 and KAFKA-2017 in 0.9.0 as both of them are trying to fix some regressions of the new consumer compared with the old consumer.
Priority-wise, I think 2017 is higher than 2397 since upon a broker shutdown / failure, all connected consumers to this broker will go through a full rebalance whereas for 2017, upon a consumer shutdown / failure it will only affect the consumers within the same group. Effort-wise, 2397 is simpler than 2017 since we need to consider what ZK data format to achieve good trade-off between storage / efficiency. For now we can work on both of them in parallel: Onur already has a patch for 2397 that Jason is reviewing, I will re-start working on 2017.
