> AbstractFetcherManager shutdown speedup

> Key: KAFKA-4319
> URL: https://issues.apache.org/jira/browse/KAFKA-4319
> Project: Kafka
> Issue Type: Improvement
> Reporter: Alexey Ozeritskiy
>
> While a shutdown proccess, AbstractFetcherManager closed all worker-threads
> sequentially which slows the final time of shutdown dramatically on huge
> clusters (approximately 15 minutes for 100 nodes, for example).
> This can be improved by parallel mode. On the first stage
> AbstractFetcherManager can send the stop signal and then join all the workers
> to the thread
