[jira] [Created] (STORM-2724) ExecutorService in WaterMarkEventGenerator never shutdown

Jungtaek Lim created STORM-2724:
-----------------------------------

             Summary: ExecutorService in WaterMarkEventGenerator never shutdown
                 Key: STORM-2724
                 URL: https://issues.apache.org/jira/browse/STORM-2724
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-client, storm-core
    Affects Versions: 1.0.4, 1.1.1
            Reporter: Jungtaek Lim
            Assignee: Jungtaek Lim


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-*.
