Stephan Ewen created FLINK-4809: ----------------------------------- Summary: Operators should tolerate checkpoint failures Key: FLINK-4809 URL: https://issues.apache.org/jira/browse/FLINK-4809 Project: Flink Issue Type: Sub-task Components: State Backends, Checkpointing Reporter: Stephan Ewen Fix For: 1.2.0
Operators should try/catch exceptions in the synchronous and asynchronous part of the checkpoint and send a {{DeclineCheckpoint}} message as a result. The decline message should have the failure cause attached to it. The checkpoint barrier should be sent anyways as a first step before attempting to make a state checkpoint, to make sure that downstream operators do not block in alignment. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
