[jira] [Created] (KAFKA-4319) AbstractFetcherManager shutdown speedup

Alexey Ozeritskiy created KAFKA-4319:
----------------------------------------

             Summary: 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
