> We have a job of Flink 1.11.0 running on YARN that reached FAILED state 
> because its jobmanager lost leadership during a ZK full GC. But after the ZK 
> connection was recovered, somehow the job was reinitiated again with no 
> checkpoints found in ZK, and hence an earlier savepoint was used to restore 
> the job, which rewound the job unexpectedly.
>   
>  For details please see the jobmanager logs in the attachment.
