> When a job start firstly, we can find 'assignPartitions' from log。but if source recover from state, we can not distinguish the newPartitions is from timed discover thread or from reader task state.  
> We can add a helper log to distinguish and confirm the reader using split state in recover situation.  it's very useful for troubleshooting.
