Konstantin Knauf updated FLINK-15731:
-------------------------------------
Description:
Currently, when a Job is {{stopped}} in-progress checkpoints are aborted and
afterwards a synchronous savepoint is started.
Since the number of tolerable checkpoint failures is 0 per default (see
{{org.apache.flink.streaming.api.environment.CheckpointConfig#getTolerableCheckpointFailureNumber}}),
this triggers a restart of the job if there are any ongoing checkpoints.
In consequence, the stop call only triggers a failover of the job instead of
stopping the job, if there is an ongoing checkpoint (or savepoint).
Possible Options would be:
a) change default of tolerable checkpoint failures to at least the max number
of concurrent checkpoints
b) do not count checkpoint failures due to the stop action when checking
against tolerable checkpoint failures
c) do not abort pending checkpoints when stopping a job, but queue the
synchronous savepoint after all current in-progress checkpoints
