Subject [jira] [Created] (FLINK-2462) Wrong exception reporting in streaming jobs
Date Sun, 02 Aug 2015 15:13:04 GMT
Stephan Ewen created FLINK-2462:

             Summary: Wrong exception reporting in streaming jobs
                 Key: FLINK-2462
                 URL: https://issues.apache.org/jira/browse/FLINK-2462
             Project: Flink
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 0.10
            Reporter: Stephan Ewen
            Priority: Blocker
             Fix For: 0.10

When streaming tasks are fail and are canceled, they report a plethora of followup exceptions.

The batch operators have a clear model that makes sure that root causes are reported, and
followup exceptions are not reported. That makes debugging much easier.

A big part of that is to have a single consistent place that logs exceptions, and that has
a view of whether the operation is still running, or whether it has been canceled.
