Subject [jira] (FLINK-4810) Checkpoint Coordinator should fail ExecutionGraph after "n" unsuccessful checkpoints
Date Tue, 31 Jan 2017 17:48:52 GMT

-----------------------------------------------

bq.numUnsuccessfulCheckpointsTriggers
Already we have this in Checkpoint Coordinator. So we could safely use this to compare against
the configured 'n' and trigger a fail on the ExecutionGraph ? - Ping [~StephanEwen]?

> The Checkpoint coordinator should track the number of consecutive unsuccessful checkpoints.
> If more than {{n}} (configured value) checkpoints fail in a row, it should call {{fail()}}
on the execution graph to trigger a recovery.
