> CompactFileWriter won't emit EndCheckpoint with Long.MAX_VALUE checkpointId
> even though the inputs end.
> It will cause data lose. For example, after completing checkpoint 5,
> CompactFileWriter write some file, then the inputs end, but it won't emit
> EndCheckpoint with Long.MAX_VALUE checkpointId, so the downstream operator
> won't do the compaction for the files which means these files are invisible.
