----------------------------------
Summary: Improve error handling of sender task failures
Key: FLINK-1955
URL: https://issues.apache.org/jira/browse/FLINK-1955
Project: Flink
Issue Type: Improvement
Components: Distributed Runtime
Affects Versions: master
Reporter: Ufuk Celebi
Currently, if a sender task fails, the produced partition is silently released.
We want:
* Produced result partition becomes erroneous with a SenderFailedException
* Receiver cancels itself when encountering the SenderFailedException
* May also be cancelled by the JobManager (if that call is faster than the
detection of the failed sender)
* This closes the Netty channel
