isServerHostingIsolatedTables

boolean isServerHostingIsolatedTables(BalancerClusterState cluster,
 int serverIdx)

getValidationLevel

RegionPlanConditional.ValidationLevel getValidationLevel()

Description copied from class: RegionPlanConditional

Returns a RegionPlanConditional.ValidationLevel that is appropriate for this conditional.

Specified by:

getValidationLevel in class RegionPlanConditional

Returns:

the validation level

getCandidateGenerators

List<RegionPlanConditionalCandidateGenerator> getCandidateGenerators()

Description copied from class: RegionPlanConditional

Get the candidate generator(s) for this conditional. This can be useful to provide the balancer with hints that will appease your conditional. Your conditionals will be triggered in order.

Specified by:

getCandidateGenerators in class RegionPlanConditional

Returns:

the candidate generator for this conditional

isViolatingServer

public boolean isViolatingServer(RegionPlan regionPlan,
 Set<RegionInfo> serverRegions)

Specified by:

isViolatingServer in class RegionPlanConditional
