Stephan Ewen created FLINK-20413:
------------------------------------
Summary: Sources should add splits back in "resetSubtask()",
rather than in "subtaskFailed()".
Key: FLINK-20413
URL: https://issues.apache.org/jira/browse/FLINK-20413
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 1.12.0
Because "subtaskFailed()" has no strong order guarantees with checkpoint
completion, we need to return failed splits in "resetSubtask()" instead.
See FLINK-20396 for a detailed explanation of the race condition.
