[GitHub] spark pull request #20677: Event time can't be greater then processing time....

GitHub user deil87 opened a pull request:

    https://github.com/apache/spark/pull/20677

    Event time can't be greater then processing time. 12:21, owl. Mistake…

    … on image.
    
    ## What changes were proposed in this pull request?
    
    There is an error on image. Point 12:21 for owl can't have 12:19 processing time. Consequently new watermark should be computed on another data (12:15, cat). Donkey still will be rejected I suppose but I'm not sure whether those watermarks inclusive or exclusive. If watermark is set to 12:05 then I guess intermediate state for window 11:55(inclusive)-12:05(exclusive) could be cleared and there is no place for Donkey anymore. You need to change image and depending on how you will change it you need to adjust the text.
    
    ## How was this patch tested?
    No tests for docs.

    @deil87 if you're willing to just edit the PNG as best you can you can proceed that way. I don't think @tdas is active anymore

    This patch needs to be changed before it can be merged. It is an image that involved in mistake and I don't have sources for image to change it nicely. Admins should verify and suggest next actions.

    I agree. The (12:14, dog) event at 12:12 also happens "early". I suppose it could have been intentional, if the idea is to illustrate disagreement about time between the event producer and stream processor, but I'm not sure. At the least, it is an unnecessary twist, and suspect the example would be better without it.
    
    @tdas do you have the source for the image?

    When we are reading documentation not for example learning on the courses we do not expect such intentional mistakes.
