-----------------------------------
Summary: Chained streaming operators should not throw chained
exceptions
Key: FLINK-2067
URL: https://issues.apache.org/jira/browse/FLINK-2067
Project: Flink
Issue Type: Bug
Components: Streaming
Reporter: Stephan Ewen
The exceptions that come from chained operators have an non-intuitive chaining
structure, that makes the stack traces harder to understand.
For every chained task, there is a "Failed to forward record" exception, before
the actual exception comes as a cause.
In the Batch API, we use a special "ExceptionInChainedStubException" that is
recognized and un-nested to make chained operator exceptions surface as root
exceptions.
We should do the same for the streaming API.
