             Summary: Task duration not updating for running tasks
                 Key: SPARK-29596
                 URL: https://issues.apache.org/jira/browse/SPARK-29596
             Project: Spark
          Issue Type: Bug
          Components: Web UI
    Affects Versions: 2.4.2
            Reporter: Bharati Jadhav


When looking at the task metrics for running tasks in the task table for the 
related stage, the duration column is not updated until the task has succeeded. 
The duration values are reported empty or 0 ms until the task has completed. 
This is a change in behavior, from earlier versions, when the task duration was 
continuously updated while the task was running. The missing duration values 
can be observed for both short and long running tasks and for multiple 
applications.

 

To reproduce this, one can run any code from the spark-shell and observe the 
missing duration values for any running task. Only when the task succeeds is 
the duration value populated in the UI.
