> This related to fault tolerance implementation in PR-1251.
> Currently recovery logic in IMRU driver is to wait for all task to move to a final state (failed or completed) before restarting the job check AreAllTasksInFinalState() in TryRecovery() method)
> We've seen driver hanging for a long time waiting for few last tasks finalize.
> Aborting tasks should be quick, so there is bug there, but we also can add logic in driver not to wait for all tasks to complete.
> For instance: if 5% of tasks did not report final state withing expected period, release corresponding evaluators and proceed with new job retry.
