I won't be available for next 2 to 3 hours. So feel free to decide based on
your convenience in case you need to make the RC candidate for 1.3 release. I
am sorry that I could not make an initial commit that took care of things
properly, should have been more careful. Thanks for the opportunity.
> Incorrect sorting of completed checkpoints in
> ZooKeeperCompletedCheckpointStore
> -------------------------------------------------------------------------------
>
> Key: FLINK-6284
> URL: https://issues.apache.org/jira/browse/FLINK-6284
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Reporter: Xiaogang Shi
> Priority: Blocker
> Fix For: 1.3.0
>
>
> Now all completed checkpoints are sorted in their paths when they are
> recovered in {{ZooKeeperCompletedCheckpointStore}} . In the cases where the
> latest checkpoint's id is not the largest in lexical order (e.g., "100" is
> smaller than "99" in lexical order), Flink will not recover from the latest
> completed checkpoint.
> The problem can be easily observed by setting the checkpoint ids in
> {{ZooKeeperCompletedCheckpointStoreITCase#testRecover()}} to be 99, 100 and
> 101.
> To fix the problem, we should explicitly sort found checkpoints in their
> checkpoint ids, without the usage of
> {{ZooKeeperStateHandleStore#getAllSortedByName()}}
