Piotr Nowojski closed FLINK-17012.
----------------------------------
Fix Version/s: 1.13.0
Release Note: Task's RUNNING state was split into two states: RECOVERING
and RUNNING. Task is RECOVERING while state is initialising and in case of
unaligned checkpoints, until all of the in-flight data has been recovered.
Resolution: Fixed
Merged to master as c0c156bd638, 22c41b06b73 and dbf1221debe
> Expose stage of task initialization

>
> Currently a task switches to running before fully initialized, does not take
> state initialization and operator initialization(#open ) in to account, which
> may take long time to finish. As a result, there would be a weird phenomenon
> that all tasks are running but throughput is 0.
> I think it could be good if we can expose the initialization stage of tasks.
> What to you think?
