> Pipelined region failover should skip restarting tasks in CREATED

> Key: FLINK-19712
> URL: https://issues.apache.org/jira/browse/FLINK-19712
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Affects Versions: 1.12.0
> Reporter: Zhu Zhu
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.12.0
>
>
> When a task fails and it is pipelined region failover strategy, all tasks in
> the region of the failed task and in the downstream regions will be canceled
> for later re-scheduling. However, these tasks can be still in CREATED state
> so that there is no need to cancel these tasks. Skipping canceling these
> tasks can speed up the failover and reduce a lot of unnecessary CANCELING
> logs.
