Wenchen Fan reassigned SPARK-29298: ----------------------------------- Assignee: Lantao Jin > Separate block manager heartbeat endpoint from driver endpoint > -------------------------------------------------------------- > > Key: SPARK-29298 > URL: https://issues.apache.org/jira/browse/SPARK-29298 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 3.0.0 > Reporter: Lantao Jin > Assignee: Lantao Jin > Priority: Major > > Executor's heartbeat will send synchronously to BlockManagerMaster to let it > know that the block manager is still alive. In a heavy cluster, it will > timeout and cause block manager re-register unexpected. > This improvement will separate a heartbeat endpoint from the driver endpoint. > In our production environment, this is really helpful to prevent executors > from unstable up and down. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
