> Key: FLINK-18063
> URL: https://issues.apache.org/jira/browse/FLINK-18063
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.11.0
> Reporter: Zhijiang
> Assignee: Zhijiang
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.11.0, 1.12.0
>
>
> In the handle of CheckpointBarrierUnaligner#processEndOfPartition, it only
> aborts the current checkpoint by judging the condition of pending checkpoint
> from task thread processing, so it will miss one scenario that checkpoint
> triggered by notifyBarrierReceived from netty thread.
> The proper fix should also judge the pending checkpoint inside
> ThreadSafeUnaligner in order to abort it and reset internal variables in case.
