zhijiangW opened a new pull request #12460:
URL: https://github.com/apache/flink/pull/12460
## What is the purpose of the change
In `CheckpointBarrierUnaligner#processCancellationBarrier` and
`CheckpointBarrierUnaligner#processEndOfPartition`, we only considered the
pending checkpoint triggered by #processBarrier from task thread to abort it.
Actually the checkpoint might also be triggered by #notifyBarrierReceived
from netty thread in race condition, so we should also handle properly to abort
it.
