Stephan Ewen created FLINK-2519: ----------------------------------- Summary: BarrierBuffers get stuck infinitely when some inputs end early Key: FLINK-2519 URL: https://issues.apache.org/jira/browse/FLINK-2519 Project: Flink Issue Type: Bug Components: Streaming Affects Versions: 0.10 Reporter: Stephan Ewen Assignee: Stephan Ewen Priority: Blocker Fix For: 0.10
When some sources exit early, the barrier buffer may start an alignment, but will never complete it, because some inputs never deliver a checkpoint barrier. [FLINK-2515] mitigates most of the problem, by not starting checkpoints any more when some sources already finished. When a checkpoint is started while a source is finishing, the barrier buffer may still align infinitely. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
