> When resource requirement changes in pod phase, shim will update locally and
> core-scheduler doesn't know it.
> Web and core-scheduler shows resource requirement changed when pod phase
> transited from initialization to running state
> Any case?
> This situation happens in YUNIKORN-706 .
> Core-scheduler creates allocationAsk which is stable and calculated from
> containers.
> If initcontainer resource requirements replace some containers requirements,
> core-scheduler will create allocationAsk and see it as fixed allocation and
> ignore resource requirement changed when pod phase transited from
> initialization to running state.
