Dongjoon Hyun updated SPARK-30623: ---------------------------------- Affects Version/s: (was: 2.4.4) > Spark external shuffle allow disable of separate event loop group > ----------------------------------------------------------------- > > Key: SPARK-30623 > URL: https://issues.apache.org/jira/browse/SPARK-30623 > Project: Spark > Issue Type: Bug > Components: Shuffle > Affects Versions: 3.0.0 > Reporter: Thomas Graves > Priority: Major > > In SPARK-24355 changes were made to add a separate event loop group for > processing ChunkFetchRequests , thisĀ allow fors the other threads to handle > regular connection requests when the configuration value is set. This however > seems to have added some latency (see pr 22173 comments at the end). > To help with this we could make sure the secondary event loop group isn't > used when the configuration of > spark.shuffle.server.chunkFetchHandlerThreadsPercent isn't explicitly set. > This should result in getting the same behavior as before. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
