------------------------------------
>From the detail log, the job has 3 compact-operator(streaming-writer) do the

And thus when read out from the compaction files, we found the data lost.
I think this test failed because the source operator(ParallelFiniteTestSource)
is still 3 parallelism rather than single parallelism. If the source is
multiple parallelism and the source will end in test(in real case, the source
won't stop), after one source subtask received endInput，the other source
subtask is still waiting checkpoint or running, this situation may lead this
problem.
