Apache Spark reassigned SPARK-7795: ----------------------------------- Assignee: (was: Apache Spark) > Speed up task serialization in standalone mode > ---------------------------------------------- > > Key: SPARK-7795 > URL: https://issues.apache.org/jira/browse/SPARK-7795 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 1.3.1 > Reporter: Akshat Aranya > > My experiments with scheduling very short tasks in standalone cluster mode > indicated that a significant amount of time was being spent in scheduling the > tasks (>500ms for 256 tasks). I found that most of the time was being spent > in creating a new instance of serializer for each task. Changing this to just > one serializer brought down the scheduling time to 8ms. -- 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
