Mukul Murthy created SPARK-25449: ------------------------------------ Summary: Don't send zero accumulators in heartbeats Key: SPARK-25449 URL: https://issues.apache.org/jira/browse/SPARK-25449 Project: Spark Issue Type: Task Components: Spark Core Affects Versions: 2.4.0 Reporter: Mukul Murthy
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
