>             Project: Flink
>          Issue Type: Sub-task

>            Priority: Major

> After recovery we should skip the execution of fully finished operators to keep consistent:
>  # For sources (including legacy source and new source), they should directly emit EndOfPartition.
>  # For both source and non-source operators, their lifecycle methods like open/endOfInput/close should be skipped.
