LantaoJin commented on issue #25971: [SPARK-29298][CORE] Separate block manager heartbeat endpoint from driver endpoint URL: https://github.com/apache/spark/pull/25971#issuecomment-552389230 I spent much more attention on the driver death since we use thriftserver as long running service. So the failed task/jobs may be retried successful, or resubmitted by upper layer scheduler tools/users. But remarkably the driver (thriftserver) can live longer and more stable with this patching. @Ngone51 Image this, in our production, driver will be busy but not be busy all its life time (unlike pressure testing), jobs/tasks may fail and executors may lost sometimes. For a long running service, we can endure jobs/tasks failed as long as driver is alive. But we can not accept the service always enters downtime once mass executors lost.
