> Support task revocation
> -----------------------
>
> Key: FLINK-10573
> URL: https://issues.apache.org/jira/browse/FLINK-10573
> Project: Flink
> Issue Type: Sub-task
> Components: JobManager
> Reporter: JIN SUN
> Assignee: JIN SUN
> Priority: Major
> Fix For: 1.7.0
>
>
> In Batch Mode, When a downstream task has a partition missing failure, which
> indicate the output of upstream task has been lost. To make the job success
> we need to rerun the upstream task to reproduce the data, which we call task
> revocation (revoke the success of upstream task)
> For revocation, we need to identify the partition missing issue, and it is
> better to detect the missing partition accurately:
> * Ideally, it makes things much easier if we get a specific exception
> indicating that the data source is missing
> * When a task got an IOException, it doesn’t mean the source data has
> issues. It might also be related to target task, such as that the target task
> has network issues.
> * If multiple tasks cannot read the same source, it is highly likely the
> source data is missing.
