Jiasheng Wang updated KAFKA-2158:
---------------------------------
Status: Open (was: Patch Available)
> Close all fetchers in AbstractFetcherManager without blocking
> -------------------------------------------------------------
>
> Key: KAFKA-2158
> URL: https://issues.apache.org/jira/browse/KAFKA-2158
> Project: Kafka
> Issue Type: Improvement
> Components: core
> Reporter: Jiasheng Wang
>
> def closeAllFetchers() {
> mapLock synchronized {
> for ( (_, fetcher) <- fetcherThreadMap) {
> fetcher.shutdown()
> }
> fetcherThreadMap.clear()
> }
> }
> It is time consuming for closeAllFetchers() in AbstractFetcherManager.scala
> because each time a fetcher calls shutdown method it will block until
> awaitShutdown() returns. As a result it will slow down the restart of kafka
> service.
