Wilfred Spiegelenburg commented on YUNIKORN-241:
------------------------------------------------
PR opened to fix request sorting only: it fixes priority sorting and adds a
simple fifo policy. Request sorting is now configurable.
Fixed issues:
- minimum value for priority is 0
- priorities are sorted fifo if they are the same (fixes random order within
priority set)
- requests can also just be sorted fifo (ignoring priorities)
> fix request sorting

> Project: Apache YuniKorn

> Reporter: Wilfred Spiegelenburg

> The requests are currently sorted based on priority.
> The sorting within requests with the same priority is broken due to the fact
> that the requests are stored in a map which gives back requests in a random
> order. This means that in the default setup requests will not be consistently
> sorted.
> If requests with the same priority are sorted we should be able to rely on
> the same result always. Currently we cannot.
