Work Description: rohdesamuel commented on pull request #10035:
[BEAM-8581] and [BEAM-8582] watermark and trigger fixes
URL: https://github.com/apache/beam/pull/10035
The GeneralTriggerDriver does not put watermark holds on timers, leading to
the ontime empty pane being considered late data.
The DefaultTrigger and AfterWatermark do not clear their timers after the
watermark passed the end of the endow, leading to duplicate records being
emitted.
