Jiayi-Liao opened a new pull request #13412:
URL: https://github.com/apache/flink/pull/13412
#12956 What is the purpose of the change
Users may execute heavy I/O operations in `finalizeOnMaster` function,
which may block the operations in main executor such as client's request and
heartbeats. This change is to move the job vertex's `finalizeOnMaster` call
into dispatcher's IO executor, and transition the job status in main executor
after all the `finalizeOnMaster` operations finish.
## Brief change log
Use `CompletableFuture.runAsync` to execute the `finalizeOnMaster` in
`ioExecutor`.
## Verifying this change
The current unit testing in `FinalizeOnMasterTest` and `MiniClusterITCase`
should cover this change.
