Joshua Cohen commented on AURORA-1672:
--------------------------------------
This is what happens when I diagnose issues with a toddler on my lap. Obviously
there's no such thing as a non-existent port, as the act of referencing is
enough to ensure it's assigned. Yet this process itself does, in fact, seem to
be what triggers the problem. More investigation is needed obviously.
> Duplicate task events displayed in UI
> -------------------------------------
>
> Key: AURORA-1672
> URL: https://issues.apache.org/jira/browse/AURORA-1672
> Project: Aurora
> Issue Type: Task
> Components: Scheduler
> Reporter: Joshua Cohen
> Assignee: Joshua Cohen
> Priority: Blocker
> Attachments: Example of duplicate task events.png
>
>
> While working on the unified containerizer support, I noticed that I was
> seeing duplicate task events in the scheduler UI. On digging further, these
> events were present in the DB as well. Initially I thought it was related to
> the storage changes for task images, but I was able to reproduce on a sha
> before those changes were introduced.
> I ran a git bisect to see what commit introduced this bug and it pointed to:
> https://github.com/apache/aurora/commit/915459dac76ed0732addce87420a4ba51d916de8
> It's not immediately obvious to me how that change is causing this,
> especially since setting {{-populate_discovery_info=false}} in
> {{aurora-scheduler.conf}} does *not* fix the problem.
