Apache Spark commented on SPARK-21474: -------------------------------------- User 'raajay' has created a pull request for this issue: https://github.com/apache/spark/pull/18683 > Make number of parallel fetches from a reducer configurable > ----------------------------------------------------------- > > Key: SPARK-21474 > URL: https://issues.apache.org/jira/browse/SPARK-21474 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 2.2.0 > Reporter: Raajay Viswanathan > Priority: Minor > Labels: configuration-addition > Original Estimate: 168h > Remaining Estimate: 168h > > Currently the number of parallel fetches is hard-coded to 5. As a result the > size of each fetch request is fixed at 1/5th of maxSizeInFlights. Since, > chunks are requested in bursts of fetchRequests; the size of a burst to a > single shuffle service can be high for large maxSizeInFlight -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
