[jira] [Created] (FLINK-7364) Log exceptions from user code in streaming jobs

Elias Levy created FLINK-7364:
---------------------------------

             Summary: Log exceptions from user code in streaming jobs
                 Key: FLINK-7364
                 URL: https://issues.apache.org/jira/browse/FLINK-7364
             Project: Flink
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 1.3.1
            Reporter: Elias Levy


Currently, if an exception arises in user supplied code within an operator in a streaming job, Flink terminates the job, but it fails to record the reason for the termination.  The logs do not record that there was an exception at all, much less recording the type of exception and where it occurred.  This makes it difficult to debug jobs without implementing exception recording code on all user supplied operators.
