Uses of VariableContext in org.apache.hadoop.yarn.server.resourcemanager.placement.csmappingrule

Methods in org.apache.hadoop.yarn.server.resourcemanager.placement.csmappingrule with parameters of type VariableContext

Modifier and Type	Method	Description
MappingRuleResult	MappingRule.evaluate(VariableContext variables)	This method evaluates the rule, and returns the MappingRuleResult, if the rule matches, skip action otherwise.
MappingRuleResult	MappingRuleAction.execute(VariableContext variables)	This method is the main logic of the action, it shall determine based on the mapping context, what should be the action's result.
abstract MappingRuleResult	MappingRuleActionBase.execute(VariableContext variables)	This method is the main logic of the action, it shall determine based on the mapping context, what should be the action's result.
MappingRuleResult	MappingRuleActions.PlaceToQueueAction.execute(VariableContext variables)	This method is the main logic of the action, it will replace all the variables in the queuePattern with their respective values, then returns a placementResult with the final queue name.
MappingRuleResult	MappingRuleActions.RejectAction.execute(VariableContext variables)	Reject action will unconditionally return a reject result.
MappingRuleResult	MappingRuleActions.VariableUpdateAction.execute(VariableContext variables)	This execute is a bit special, compared to other actions, since it does not affect the placement of the application, but changes the variable context.
boolean	MappingRuleMatcher.match(VariableContext variables)	Returns true if the matcher matches the current context.
boolean	MappingRuleMatchers.AndMatcher.match(VariableContext variables)	This match method will go through all the provided matchers and call their match method, if all match we return true.
boolean	MappingRuleMatchers.MatchAllMatcher.match(VariableContext variables)	The match will return true in all cases, to match all submissions.
boolean	MappingRuleMatchers.OrMatcher.match(VariableContext variables)	This match method will go through all the provided matchers and call their match method, if any of them match we return true.
boolean	MappingRuleMatchers.UserGroupMatcher.match(VariableContext variables)	The method will match (return true) if the user is in the provided group.
boolean	MappingRuleMatchers.VariableMatcher.match(VariableContext variables)	The method will replace all variables in the value, then compares this substituted value against the variable's value, if they match we return true.
