Konstantin Knauf commented on FLINK-3669:
-----------------------------------------
[~aljoscha] Hmpf. You're right. I was actually a little bit suspicious, that I
did not need any additional state ;) Anyway, I pushed a new version. This time
also with modifications to StreamTask to set deleteOnCancelPolicy(true).

Aside: A lot of my Travis-Builds fail with a compilation problem in
flink-connector-elasticsearch2 even on master (e.g.
https://travis-ci.org/knaufk/flink/builds/125920011 3 und 5). What's the reason?
> WindowOperator registers a lot of timers at StreamTask

> Key: FLINK-3669
> URL: https://issues.apache.org/jira/browse/FLINK-3669
> Project: Flink
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.0.1
> Reporter: Aljoscha Krettek
> Assignee: Konstantin Knauf
> Priority: Blocker
>
> Right now, the WindowOperator registers a timer at the StreamTask for every
> processing-time timer that a Trigger registers. We should combine several
> registered trigger timers to only register one low-level timer (timer
> coalescing).
