Description

I have seen a topology with event time windowing never terminated on local mode. While looking into detail on thread dump I found only one non-daemon thread prevents process to be not finished: executorService in WaterMarkEventGenerator.

Btw, I dumped thread via jstack but impossible to find from jstack result because it doesn't have thread factory hence thread name is pool-*.
