[jira] [Created] (FLINK-2420) OutputFlush thread in stream writers does not propagate exceptions

Stephan Ewen created FLINK-2420:
-----------------------------------

             Summary: OutputFlush thread in stream writers does not propagate exceptions
                 Key: FLINK-2420
                 URL: https://issues.apache.org/jira/browse/FLINK-2420
             Project: Flink
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 0.10
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 0.10


The output flush thread only throws exceptions that it encountered. This simply lets the thread die, when the exceptions reach the root of the stack.

The exceptions never reach the actual writer code. That way, exceptions that only happen on flush (or the last flush) would never be detected.
