Shixiong Zhu reassigned SPARK-27394: ------------------------------------ Assignee: Shixiong Zhu > The staleness of UI may last minutes or hours when no tasks start or finish > --------------------------------------------------------------------------- > > Key: SPARK-27394 > URL: https://issues.apache.org/jira/browse/SPARK-27394 > Project: Spark > Issue Type: Bug > Components: Web UI > Affects Versions: 2.4.0, 2.4.1 > Reporter: Shixiong Zhu > Assignee: Shixiong Zhu > Priority: Major > > Run the following codes on a cluster that has at least 2 cores. > {code} > sc.makeRDD(1 to 1000, 1000).foreach { i => > Thread.sleep(300000) > } > {code} > The jobs page will just show one running task. > This is because when the second task event calls > "AppStatusListener.maybeUpdate" for a job, it will just ignore since the gap > between two events is smaller than `spark.ui.liveUpdate.period`. > After the second task event, in the above case, because there won't be any > other task events, the Spark UI will be always stale until the next task > event gets fired (after 300 seconds). -- 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
