Summary: Race condition in Spark k8s Pod lifecycle management that leads to shutdowns Key: SPARK-33711 URL: https://issues.apache.org/jira/browse/SPARK-33711 Project: Spark Issue Type: Bug Components: Kubernetes Affects Versions: 3.0.1, 3.0.0, 2.4.7 Reporter: Attila Zsolt Piros Watching a POD (ExecutorPodsWatchSnapshotSource) informs about single POD changes which could wrongfully lead to detecting of missing PODs (PODs known by scheduler backend but missing from POD snapshots) by the executor POD lifecycle manager. A key indicator of this is seeing this log msg: "The executor with ID [some_id] was not found in the cluster but we didn't get a reason why. Marking the executor as failed. The executor may have been deleted but the driver missed the deletion event." So one of the problem is running the missing POD detection even when a single pod is changed without having a full consistent snapshot about all the PODs (see ExecutorPodsPollingSnapshotSource). The other could be a race between the executor POD lifecycle manager and the scheduler backend. -- 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
