-----------------------------------
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.
