jayunit100 08cff0157d PredicateMetadata factory and optimization, Cleaned up some comments, 
Comments addressed, Make emptyMetadataProducer a func to avoid casting,
FakeSvcLister: remove error return for len(svc)=0.  New test for
predicatePrecomp to make method semantics explictly enforced when meta
is missing. Precompute wrapper.

HaiyangDING 41ed85479a move predicates into library (address #12744) 
DONE:
1. refactor all predicates: predicates return fitOrNot(bool) and error(Error) in which the latter is of type
	PredicateFailureError or InsufficientResourceError. (For violation of either MaxEBSVolumeCount or
        MaxGCEPDVolumeCount, returns one same error type as ErrMaxVolumeCountExceeded)
2. GeneralPredicates() is a predicate function, which includes serveral other predicate functions (PodFitsResource,
        PodFitsHost, PodFitsHostPort). It is registered as one of the predicates in DefaultAlgorithmProvider, and
        is also called in canAdmitPod() in Kubelet and should be called by other components (like rescheduler, etc)
        if necessary. See discussion in issue #12744
3. remove podNumber check from GeneralPredicates
4. HostName is now verified in Kubelet's canAdminPod(). add TestHostNameConflicts in kubelet_test.go
5. add getNodeAnyWay() method in Kubelet to get node information in standaloneMode

TODO:
1. determine which predicates should be included in GeneralPredicates()
2. separate GeneralPredicates() into:
	a. GeneralPredicatesEvictPod() and
	b. GeneralPredicatesNotEvictPod()
3. DaemonSet should use GeneralPredicates()

Hongchao Deng ae88f08af0 Scheduler: replace system modeler with scheduler cache 2016-03-14 09:03:41 -07:00

Hongchao Deng 9236e4a0b4 scheduler: change fit predicates and priority func as needed for optimization 2016-02-09 09:38:28 -08:00
Oleg Shaldybin 3a36dfb306 Minor selectHost optimization in scheduler 
Instead of sorting hosts by score, find max score and choose one of
the hosts with max score directly. Saves a little time on sorting and
avoids extra copying of HostPriorityList entries.

Test had to be updated as one of the test cases relied on having a
stable order from pre-sorting.

tummychow 78ce5da988 Move util.StringSet into its own package 
A lot of packages use StringSet, but they don't use anything else from
the util package. Moving StringSet into another package will shrink
their dependency trees significantly.

hurf 6203ce9f85 Move pkg/scheduler to plugin/pkg/scheduler 
As the TODO in plugin/pkg/scheduler/scheduler.go described:

move everything from pkg/scheduler into this package. Remove
references from registry.
