Shixiong Zhu updated SPARK-25449: --------------------------------- Issue Type: Improvement (was: Task) > Don't send zero accumulators in heartbeats > ------------------------------------------ > > Key: SPARK-25449 > URL: https://issues.apache.org/jira/browse/SPARK-25449 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 2.4.0 > Reporter: Mukul Murthy > Priority: Major > > Heartbeats sent from executors to the driver every 10 seconds contain metrics > and are generally on the order of a few KBs. However, for large jobs with > lots of tasks, heartbeats can be on the order of tens of MBs, causing tasks > to die with heartbeat failures. We can mitigate this by not sending zero > metrics to the driver. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
