[ https://issues.apache.org/jira/browse/SPARK-1239?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Josh Rosen updated SPARK-1239: -- Assignee: Josh Rosen (was: Kostas Sakellis) I'm re-assigning this to me since I've been working in this code recently and plan to completely re-write MapOutputStatusTracker to address this and a few other issues. I like the idea of piggybacking the status on the task launching RPC itself; if we took the approach of having reducers specify their reduce ids when fetching the statuses, then this would add an extra RPC for every task launch, which could result in a big latency increase. > Don't fetch all map output statuses at each reducer during shuffles > --- > > Key: SPARK-1239 > URL: https://issues.apache.org/jira/browse/SPARK-1239 > Project: Spark > Issue Type: Improvement > Components: Shuffle, Spark Core >Affects Versions: 1.0.2, 1.1.0 >Reporter: Patrick Wendell >Assignee: Josh Rosen > > Instead we should modify the way we fetch map output statuses to take both a > mapper and a reducer - or we should just piggyback the statuses on each task. -- This message was sent by Atlassian JIRA (v6.3.4#6332) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
