> Priority: Major
> Time Spent: 5h 40m
> Remaining Estimate: 0h
>
> In standalone, when we have a rebalance before the container has started
> successfully with the previous job model, OnJobModelExpired does a no-op. It
> happens since the stream processor doesn’t transition to RUNNING until the
> container callback gets invoked. OnJobModelExpired, assumes the processor is
> still in the REBALANCE phase and does a no-op.
>
> Often times, containers take longer time to start. Especially stateful
> containers that have large state to restore. In those scenarios, if a
> rebalance happens before the container has started successfully, processors
> in the quorum will run with inconsistent job model.
