-----------------------------------

             Summary: Instability due to pending processing timers on operator close
                 Key: FLINK-4747
                 URL: https://issues.apache.org/jira/browse/FLINK-4747
             Project: Flink
          Issue Type: Bug
          Components: Local Runtime
    Affects Versions: 1.2.0
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.2.0


Execution on finite streams can hit a concurrent processing time timer while closing operators, resulting in a timer exception.

With the recent change to eagerly report asynchronous exceptions from timers, this becomes visible even on shutdown.
