Vinod Kone updated MESOS-7774:
------------------------------
Sprint: (was: Mesosphere Sprint 59)
> Consider more clearly distinguishing "zombie" tasks from other tasks in webui
> -----------------------------------------------------------------------------
>
> Key: MESOS-7774
> URL: https://issues.apache.org/jira/browse/MESOS-7774
> Project: Mesos
> Issue Type: Improvement
> Components: webui
> Reporter: Benjamin Bannier
> Labels: mesosphere
>
> The webui's home page displays a list of active tasks; this list is
> constructed from the list of non-completed framework tasks. If a framework
> has not yet acknowledged a terminal status update, the list of "active tasks"
> can contain tasks in terminal states which is confusing to users, e.g.,
> * launch {{sleep 10}} with {{mesos-execute}}
> * after the task is launch suspend the {{mesos-execute}} process
> * after 10s the list of active tasks contains a {{FINISHED}} task
> or
> * launch {{sleep 100000}} with {{mesos-execute}}
> * after the task is launch suspend the {{mesos-execute}} process
> * kill the {{sleep}} system process
> * the list of active tasks contains a {{FAILED}} task
> The underlying issue here is that what is displayed in the webui very
> directly reflects the list of tasks in {{master}} {{Framework}} objects.
> There {{tasks}} holds tasks the master needs to track (since they might e.g.,
> still be running, or the frameworks need to be notified of status changes,
> etc.), while e.g. {{completedTasks}} holds tasks of just historic interest
> since they do not anymore require any master actions.
> Exposing this information in such an unfiltered way is likely confusing.
> While this applies to the {{state}} endpoint like it does to the webui, a fix
> should be easier to accomplish in the ui. We could there add some (visual?)
> clue that active tasks in terminal states are analogous to zombie processes.
