Stephan Ewen created FLINK-2067: ----------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
