Wilfred Spiegelenburg resolved YUNIKORN-1217.
---------------------------------------------
Resolution: Fixed
pod sorting is implemented.
I ran a couple of simple checks to see how long the sorting of a random set of
generated pods would take: 100000 pods took less than a second to sort. The
overall recovery time will not be impacted by this new sorting.
Thank you [~pbacsko] for the contribution

> When running a Spark workload with gang scheduling, the driver and executor
> pods have different annotations.
> It is critical that we process the driver first, because it has the task
> group definitions. Based on
> [https://yunikorn.apache.org/docs/next/user_guide/gang_scheduling/,] the
> executor only needs {{{}yunikorn.apache.org/taskGroupName{}}}.
> So when we add the pods in the recovery code path, we have to start with the
> driver.
