Renamed to `failurePropagationAfterTransactionTimeoutDisabled` as this is
closer to the method that controls this field.
> Don't fail TwoPhaseCommitSinkFunction when failing to commit
> ------------------------------------------------------------
>
> Key: FLINK-7784
> URL: https://issues.apache.org/jira/browse/FLINK-7784
> Project: Flink
> Issue Type: Bug
> Components: DataStream API
> Affects Versions: 1.4.0
> Reporter: Aljoscha Krettek
> Assignee: Gary Yao
> Priority: Blocker
> Fix For: 1.4.0
>
>
> Currently, {{TwoPhaseCommitSinkFunction}} will fail if committing fails
> (either when doing it via the completed checkpoint notification or when
> trying to commit after restoring after failure). This means that the job will
> go into an infinite recovery loop because we will always keep failing.
> In some cases it might be better to ignore those failures and keep on
> processing and this should be the default. We can provide an option that
> allows failing the sink on failing commits.
