Myasuka opened a new pull request #9123: [FLINK-13281] Fix the verify logic of 
AdaptedRestartPipelinedRegionStrategyNGAbortPendingCheckpointsTest
URL: https://github.com/apache/flink/pull/9123
 
 
   ## What is the purpose of the change
   
   [FLINK-13060](https://issues.apache.org/jira/browse/FLINK-13060) ensure 
FailoverStrategies should respect restart constraints. However, this change did 
not cover the 
`AdaptedRestartPipelinedRegionStrategyNGAbortPendingCheckpointsTest` which 
should also set as `FixedDelayRestartStrategy`. Currently, as the pending 
checkpoint would still be discarded due to 
`failUnacknowledgedPendingCheckpoints` within `CheckpointCoordinator`, 
`AdaptedRestartPipelinedRegionStrategyNGAbortPendingCheckpointsTest` could pass 
the test.
   
   This is actually not what we want the test did, we should actually verify 
that when region failover, pending checkpoints would be discarded.
