Kinga Marton commented on YUNIKORN-513:
---------------------------------------
After the core refactoring, the app state transition happens in the following
steps:
* New -> Accepted: when an allocationAsk is processed
* Accepted -> Starting: when the allocation is processed
* Starting -> Running: when the second allocation is processed or when the
Starting state times out.
In case of recovery, we don't have AllocationAsk, just already existing
Allocations, so the first transition is skipped. This means, that if we have
only 2 allocations, the application will not progress into the Running state.
For the recovery we need to progress it manually from New to Accepted.
> ApplicationState remains in Accepted after recovery
